WASHINGTON - Arizona Sen. John McCain, a political maverick and unflinching supporter of the war in Iraq, clinched the Republican presidential nomination Tuesday night. Barack Obama defeated Hillary Rodham Clinton in the Democratic primary in Vermont, and the two rivals dueled in Ohio, Texas and Rhode Island in a riveting race for their party's presidential nomination.
McCain, 71, gained the 1,191 delegates needed to claim the Republican nomination with a series of primary victories, completing a remarkable comeback that began in the snows of New Hampshire six weeks ago. President Bush invited him to the White House for a show of support on Wednesday.
