WASHINGTON - Not so fast, Sen. McCain.Read the whole thing...
John McCain's campaign issued a statement last week claiming the Arizona senator had surpassed the number of delegates needed to secure the GOP nomination for president, after Mitt Romney endorsed him.
John McCain sure looks like he has the nomination all but wrapped up. But he isn't there yet, and here's why:
It will take 1,191 delegates to secure the Republican nomination at the national convention this summer.
McCain has 908 delegates, including those won in primaries and caucuses as well as endorsements from party leaders who automatically attend the convention. Romney has 253, according to The Associated Press tally.
Together, that's 1,161 delegates, which could make it tempting for some to put McCain over the top Tuesday evening if he fares well in primaries in Washington state and Wisconsin. A total of 56 delegates will be at stake.
Former Arkansas Gov. Mike Huckabee has 245 delegates, placing him behind a candidate who isn't even in the race anymore. Texas Rep. Ron Paul has 14.
GOP rules, however, say McCain still has work to do.
The rules vary state to state. But in general, Romney has little authority over his delegates after he releases them. The vast majority haven't been named. Once they are, most will be free agents at the convention, free to support whomever they choose.
Huckabee has said he won't quit until somebody reaches 1,191 delegates. And a few more Huckabee victories in upcoming primaries could prove embarrassing for McCain.
