"Shrill and sarcastic political attacks may fire up the Republican base, but they don't change the fact that a McCain-Palin administration would mean four more years of failed Bush-Cheney policies," said Jim Manley, spokesman for Senate Majority Leader Harry Reid, D-Nev.

Palin attacked Democrats in her speech Wednesday night at the Republican National Convention. Democrats responded by saying Palin, the governor of Alaska, sought to distract voters who know Palin and presidential running mate Sen. John McCain, R-Ariz., can't fix America's problems, CNN reported Thursday.

Rep. Debbie Wasserman Schultz, D-Fla., called it scary that Palin made her case for the vice presidency by saying she negotiated the sale on eBay of a former Alaskan governor's state plane.

"If, God forbid, anything happens to John McCain, then we are in for a scary proposition," Wasserman Schultz said.
