McCain proposed a more than $50 billion economic plan that would eliminate taxes on unemployment benefits, guarantee 100% of all savings for 6 months, cut capital gains taxes and lower taxes on seniors tapping their retirement accounts during these tough times.
"I will increase the amount of capital losses from $3,000 to $15,000 which can be deducted from your income tax returns for 2008 and 2009," McCain said.
McCain blasted Barack Obama's economic recovery plan, but did not launch the widely criticized "guilt by associaton" attacks that triggered some ugly threatening rhetoric at recent McCain rallies.
One McCain supporter predicted Obama's lead in the polls will not materialize on election day because a lot of whites are misleading pollsters.
"There's the Tom Bradley effect that you've heard about, people say one thing in the polls and do another thing behind the curtain," said Liz Louden of King of Prussia.
McCain is due back in the Philadelphia suburbs on Thursday to continue his battle for this key swing state.
"Mr. McCain is God's player, he has been practically through crucifixion, he's been proven, he's been tested, he's a humble spirit," said Maryann Brown of Boyertown.
Sen. McCain headed to New York to raise money with running mate Sarah Palin, and to prepare for Wednesday night's final scheduled face-to-face debate with Sen. Obama.
Many experts say that is his last major chance to turn the tide.
