Mirroring a national trend, Bush's favorability rating has dropped from 63 percent in April to 49 percent today, according to the Keystone Poll conducted for the Pittsburgh Tribune-Review, the Philadelphia Daily News and the Harrisburg Patriot-News.
Among the Democratic presidential candidates, Sen. Joseph Lieberman of Connecticut is favored by 12 percent of Pennsylvania Democrats, followed by former Vermont Gov. Howard Dean with 11 percent and New York City activist Al Sharpton with 10 percent. Six other Democratic candidates finished with less than 10 percent.

The Republican president's strongest support is in Central and Southwestern Pennsylvania. It drops below 50 percent in Allegheny County and in the critical Philadelphia suburbs. It's 19 percent in heavily Democratic Philadelphia.

Still, 48 percent of Pennsylvanians say it is time for a change, compared with 44 percent who say Bush deserves re-election, Madonna said.
