McCain goes on the attack in final debate

Economic proposals spark sharp disagreement as Obama defends new plan.

Republican Sen. John McCain launched a heavy assault on Democratic Sen. Barack Obama’s judgment and experience Wednesday night, making a last-ditch effort in the final presidential debate to change the course of a campaign moving decidedly in his opponent’s favor.McCain bore in on details of Obama’s new $60 billion proposal to address the country’s economic problems, saying they would mean steep tax increases for many Americans. Under the proposal, which he unveiled Monday, Obama would offer tax breaks for companies that create jobs, eliminate penalties for early withdrawals from retirement accounts, postpone foreclosures and boost federal outlays to states and cities.“Why would you want to raise anybody’s taxes right now?” McCain asked. “We need to encourage businesses.”
