John McCain continues to close in on Barack Obama's lead in the run-up to the Democratic National Convention.

Two new national polls released Wednesday night show Obama leading McCain by 3 points, which is consistent with other recent surveys.

A Wall Street Journal/NBC News poll showed Obama leading McCain by 45-to-42 percent, down from a 6-point advantage in a similar poll a month ago.

Obama had opened up a significant advantage following his high-profile trip abroad in late July. But since then McCain has hammered him as a disconnected celebrity. The Wall Street Journal poll also found that the recent conflict between Russia and Georgia has highlighted McCain's foreign policy resume. Voters said McCain is better than Obama in handling such international crises by a margin of 52 percent to 27 percent.

The poll, taken from Aug. 15-18, had a margin of error of 3.1 percentage points.

Another poll from The New York Times/CBS News reflected an identical dynamic in the campaign.

It too showed Obama pulling 45 percent and McCain pulling 42 percent. The Illinois senator's lead was 6 points in a similar poll taken two weeks ago.

Voters in that poll said McCain was more prepared to be commander in chief. But on domestic issues, Obama was still strong. Sixty-five percent of registered voters in the poll were very or somewhat confident in Obama's economic ability, compared with 54 percent for McCain. Twice as many respondents thought Obama would improve the U.S. image abroad.

The poll, taken Aug. 15-19, had a margin of error of 3 percentage points.

The polls suggest there's still plenty of time for the candidates to pick off voters from one another, with conventions, running-mate selections and presidential debates on the horizon.

In the New York Times poll, about one in four voters said they could still change their mind by November. Only 51 percent said they've been paying a lot of attention to the campaign this year.
