Obama, McCain trade jabs over tax policies

"I am not in favor of tax cuts for the wealthy. I am in favor of leaving the tax rates alone," McCain said.

McCain charged that "Obama's secret that you don't know" is that he would increase taxes on small business revenue, which he said would lead to job cuts.

Obama shot back, saying "the Straight Talk Express lost a wheel on that one."

"Let's be clear about my tax plan and Senator McCain's," he said. "I want to provide a tax cut for 95 percent of Americans."

Earlier, McCain said the system in Washington "cries out for bipartisanship" and pushed his record as a reformer.

He and Obama were asked how voters could trust either one of them to fix the economy when both parties contributed to the financial crisis.
