Yesterday's primaries in Ohio, Texas, Vermont and Rhode Island saw John McCain assume the mantle of the Republican presidential nominee, with commanding victories in all but Texas, and Mike Huckabee's announcement that he's withdrawing from the race. "It's now important that we turn our attention not to what could have been or what we wanted to have been, but now what must be -- and that is a united party," Huckabee told told supporters in Dallas. After it became clear that McCain would sweep all four races, Barack Obama called McCain to congratulate him on winning the nomination, adding that he was looking forward to facing the Arizona senator in the general election. more ›

In a race that may be a precursor to the Ohio and Texas Democratic primaries in March, Barack Obama won a decisive victory in Wisconsin last night, leading Hillary Clinton by nearly 20 points. He also won Hawaii, taking over 75 percent of the vote in a state where he had campaigned as a "native son." His victories last night mark his ninth and tenth consecutive primary or caucus wins and put his pledged delegate count at 1,140. Clinton has 1,005 pledged delegates. When you add in committed superdelegates, Obama leads Clinton 1,301 to 1,239, with John Edwards's 26 delegates still in play. Chris Bowers at OpenLeft points out that Clinton has now surpassed Jessee Jackson's 1988 total of 1218 delegates. 1988 saw the highest number of delegates ever won by a Democrat who did not win the nomination. more ›
