As members of Congress head back to their districts for the August recess, they could be met by the same rowdy town halls that rocked the national healthcare debate last summer.

But this summer, record-breaking government spending would fuel the voter uprising, conservatives say.

"This is democracy's way of making a midcourse correction and providing checks and balances to a runaway federal government," Sen. John Cornyn, R-Texas, told Fox News.

Led by House Speaker Nancy Pelosi, D-Calif., and Senate Majority Leader Harry Reid, D-Nev., Democrats face two tough decisions with big economic and political consequences.

First, billions in Bush-era tax cuts are set to expire with rates going back up – potentially slowing the recovery unless Congress extends the cuts. Separately, 13 massive government spending or appropriations bills to fund the government next year are almost certain to increase spending.

Endangered centrist Democrats are distancing themselves from their president and party's big spending. In Arkansas, Democrat Blanche Lincoln trails her GOP opponent by double digits. Her new 30-second ad speaks volumes.

"I want to show you what it's like in Washington these days," she says in the ad that shows rowdy kids in a classroom throwing cash around. "This is why I voted against giving more money to Wall Street, against the auto company bailout, against the public option health care plan."

Even some liberal Democrats are taking a pounding and considered at risk, including Washington Sen. Patty Murray, who ran as a mom in tennis shoes.

"You pushed the largest increase in federal spending ever, raised taxes on small business, you cost us jobs," says an ad paid for by the American Action Network.

Amid the attacks, a sputtering economy, and record-high federal spending, Democrats may postpone any additional spending votes until a post-election lame duck session.

"I don't think Dems are going to want some massive number on the front of every newspaper, at the top of every newscast right prior to the public voting in Nov. 2," said Larry Sabato, director of the Center for Politics at the University of Virginia.
