Former Massachusetts governor Mitt Romney, who dropped out of the Republican presidential race last week, endorsed front-runner John McCain today despite their bitterly-fought race. 

He would 'give my full support to Senator McCain's candidacy,' Romney told a news conference with McCain at his side. 

Romney also asked the 291 delegates pledged to vote for him to switch allegiance to McCain at the September Republican Party nominating convention.
