Obama blasts McCain on tax stance

By John Whitesides, Political Correspondent

WASHINGTON (Reuters) - Democrat Barack Obama took aim on Thursday at potential White House opponent John McCain, accusing the Arizona senator of switching his stance on tax cuts in order to help his bid for the Republican presidential nomination.

Obama, locked in a tight Democratic battle with Hillary Clinton for the right to face McCain in November's presidential election, noted McCain opposed President George W. Bush's tax cuts in 2001 and 2003 but now supports their extension.

"He made a decision to reverse himself on that, that was how I guess you got your ticket punched to be the Republican nominee," Obama told reporters. "But he was right then and he's wrong now."

McCain responded that he looked forward to a potential debate on taxes with Obama during a general election campaign.

"Senator Obama has stated very clearly his desire to increase Americans' taxes. That'll be one of the great debates we have if he is the nominee of his party," McCain told reporters.

Obama, Clinton and McCain took a break from the campaign trail and spent time on Thursday at their day jobs in the U.S. Senate, where they cast votes on a budget blueprint for fiscal 2009.

Obama, an Illinois senator, and Clinton, a New York senator, called a truce in their fierce Democratic battle, shaking hands on the Senate floor and sitting down together for a brief chat.

All three senators, including McCain, voted for a Democratic proposal to permanently extend a 10 percent tax rate, mostly for low-income earners, along with a child tax credit and marriage penalty relief. All were all set to expire in 2010.
