The U.S. Chamber of Commerce will use much of its remaining political war chest to get Republican voters to the polls, a source tells Power Play.

President Obama and his team went on the attack against the Chamber Thursday just as a barrage of new Chamber ads were hitting the airwaves.

The president, his fellow Democrats and allied liberal groups turned up the heat on the U.S. Chamber, claiming that because the business group accepts dues from foreign companies, they were allowing foreigners to influence U.S. elections.

The push to label the Chamber as unpatriotic came as Democratic media buyers across the country were sending some very bad news back to Washington - that the Chamber was dropping $10 million over the course of one week in competitive Senate and House races across the land.

The reaction was swift.

Speaking to a Democratic rally in Maryland, Obama cast himself and his party as the victims of foreign meddling and big business and Sen. Al Franken (D-MN) wants the Federal Election Commission to investigate the sources of Chamber funding.

The spots, which warn of job killing taxes and economic malaise, are aimed at Democrats in the Senate races in New Hampshire, Florida, Colorado, Illinois, Wisconsin, Pennsylvania, Connecticut and Missouri and two-dozen battleground House races.

In a year of big buys from outside groups, this one is the biggest one-week rollout yet.

But a Chamber source familiar with the group's election strategy tells Power Play that the group is just beginning its final election rollout, and that there's much more to come.

"If they didn't like this week, they're really going to hate the rest of October," said the Chamber insider.

The Chamber raised and set aside $75 million for the elections - that's less than the estimated $150 million that its foes in organized labor may spend this year, but arguably as effective because it is more tightly focused.

The group is quick to point out that the $75 million doesn't include any money from overseas dues.

The Chamber source wouldn't confirm any specific spending numbers, but the group has reportedly only spent or publicly committed $25 million of the $75 million total.

What about the rest of the money?

With the Republican National Committee in tough financial shape in a year that also sees remarkably high number of competitive races - a dozen in the Senate and perhaps 90 in the House - the Chamber is putting a lot more energy into ground game and getting voters to the polls.

"It's not new for [the Chamber] to do mail and calls, but I think you're going to see a lot more intensity on the ground this year," said the source. "You don't want to leave any votes on the table."

He also expects at least one more large-scale ad push, in addition to the ground game.

Obama hopes to blunt the impact of the Chamber's activities by questioning the group's patriotic allegiance and casting himself as an underdog, but he and his party have been raising questions of campaign funding since his unprecedented swipe at the Supreme Court during his State of the Union address and seem to have gotten little traction with voters.

It is an inside Washington issue all the way.

The Chamber, meanwhile, is going hyper-local with the rest of its strategy - focusing on turnout and targeting voters.

Scandal Sheets - Brown in Hot Water Over Aides' "Whore" Remark; Probe Begins on Obama Adviser's Knowledge of Political Foes' Tax Status

Brown Aide Called Whitman a "Whore"

A recording of California Democratic gubernatorial candidate Jerry Brown discussing campaign strategy with an advisor who calls Republican Meg Whitman "a whore" is further roiling the already wild Golden State race.

The L.A. Times got the tape from a police union official on whose answering machine the conversation was inadvertently recorded. Brown thought he had hung up the phone after leaving a message for a union leader, but the machine was still recording his conversation with an adviser.

Brown is complaining about a reported deal Whitman cut with public safety unions to exempt their pensions from her fiscal overhaul plans. Here's the transcript from the LAT:

BROWN: "Do we want to put an ad out? ... That I have been warned if I crack down on pensions, I will be - that they'll go to Whitman, and that's where they'll go because they know Whitman will give 'em, will cut them a deal, but I won't."SECOND MALE VOICE: "What about saying she's a whore?"

BROWN: "Well, I'm going to use that. It proves you've cut a secret deal to protect the pensions."

The Brown campaign apologized for the "salty" language.

The Whitman campaign called Brown's tacit approval of the remark "an insult to both Meg Whitman and to the women of California" and "an appalling and unforgivable smear."

IG Will Probe Claims the White House Snooped in Foes' Tax Files

Austan Goolsbee, President Obama's top economic adviser, in a conference call in August held up Koch Industries as an example of a company that exploits tax laws to avoid paying full corporate tax rates.

Now, the inspector general of the Treasury, acting at the behest of Sen. Charles Grassley (R-IA) has begun an investigation into whether Goolsbee or anyone else in the administration illegally snooped into the files of some of the president's top political opponents.

The libertarian-leaning Koch family is one of the president's most ardent political opponents, funding campaigns and academic work that opposes the Obama agenda. A summertime New York Times profile of the Kochs' activism further inflamed liberal anger at the industrialists.

Goolsbee couldn't have known precisely what Koch Industries pays in taxes or even how they file without looking at confidential IRS records.

A White House official tells FOX News' colleague Mike Emanuel that Goolsbee's statements were "not based on any review of tax filings and we will not use this example in the future."

Obama's Day - POTUS Wrestles Jobless Claims While Biden Keeps Stumping

President Obama will tour a small manufacturer in the Maryland suburbs and then make remarks on the September jobs report. If forecasts are accurate and job growth slowed again, this is a good day for Obama to stay away from Democratic candidates.

The White House announced that the president and first lady will campaign together in Cleveland for Gov. Ted Strickland on Oct. 17 - the first double-Obama event of the campaign season.

Vice President Biden is staying on the campaign trail. He heads from Minnesota to Washington where he will speak at a rally for embattled Sen. Patty Murray. Murray's Republican opponent, Dino Rossi, just announced a huge $4.4 million fundraising haul for September.

Biden is also scheduled to join Obama this weekend at a campaign rally in Philadelphia.

Poll Check - The Kids Don't Stand a Chance

A new Pew poll finds that voter interest among Democrats ages 18 to 29 are far less enthusiastic than in 2006. At this point in 2006, 47 percent of young Democrats were "giving a lot of thought" to the upcoming midterm elections. This time, it's 27 percent. Young Republican interest is up 8 points.

Among older Democrats, interest has fallen since 2006 as well, dropping from 53 percent to 43 percent. Older Republicans' interest went up from 49 percent in 2006 to 67 percent this year.

The survey also found that the gap between the GOP and Democrats among young voters returned to a more typical 20-point advantage for Democrats after the 30-point spread before the 2008 elections.

Older and more conservative voters are more enthusiastic while young voters are tuning out, even compared to 2006, to say nothing of the faded euphoria of 2008.
