New polls might be a source for some optimism among Hillary Clinton supporters even as the Democratic presidential candidate trails in the search for convention delegates.

According to a new poll from The Assocated Press, Clinton has a better chance than Barack Obama of beating Republican John McCain. The AP-Ipsos poll bolsters her argument that she is more electable in the fall than her rival for the Democratic nomination.

The survey released Monday (1,001 U.S. adults, 760 registered voters, April 23-27, +/- 3.1 percent for all adults) gives Clinton a fresh talking point as she works to convince pivotal undecided superdelegates to side with her in the drawn-out Democratic primary fight.

Clinton, who won the Pennsylvania primary last week, has gained ground this month in a hypothetical head-to-head match up with the GOP nominee-in-waiting; she now leads McCain, 50 percent to 41 percent, while Obama remains virtually tied with McCain, 46 percent to 44 percent.

And the most recent Gallup Daily tracking poll puts Clinton and Obama even in its ongoing watch of national Democratic voters. The two are tied -- for a second straight day -- at 47 percent. The survey was taken April 24-26 and released Sunday. Clinton has trailed Obama by as much as 11 points, but led briefly by one point leading into the Pennsylvania primary.

In the Gallup tracking data, Clinton also leads McCain (47-44 percent) whereas Obama and McCain are tied among U.S. national voters at 45 percent in the latest daily survey.
