Rendell praises Obama's VP pick

WASHINGTON, Aug. 24 (UPI) -- Pennsylvania Gov. Ed Rendell Sunday said an ad for likely Republican presidential nominee John McCain critical of the Democratic ticket won't do much damage.

Appearing on CBS' "Face the Nation," Rendell said the ad -- which suggests New York Sen. Hillary Clinton was "passed over" for the vice presidential slot on the Democratic ticket for "speaking the truth" about presumptive nominee Barack Obama -- will have just a "three-day life span," he said.

"When Hillary Clinton speaks (at the Democratic National Convention) on Wednesday night, she will blow this ad out of the water," said Rendell, who supported Clinton in the Democratic presidential primary against Obama and others.

Obama Saturday announced he had chosen Delaware Sen. Joe Biden to be his running mate.

Rendell said an Obama-Biden ticket is good for the Democratic Party.

"Hillary Clinton obviously has a longer relationship with a broader spectrum of voters, women voters who've been following her for a long time, but Joe Biden's going to grow on the American people very fast because he's a tremendously engaging guy, a tremendously bright guy, and a guy who's sort of Harry Truman-like: He tells it like it is," Rendell said.
