Republican Mitt Romney said on Friday he would vote for Senator Ted Cruz in Utah¡¯s presidential nominating contest, but the party¡¯s 2012 election standard-bearer stopped short of an official endorsement as he urged voters to deny the nomination to front-runner Donald Trump.

In a Facebook post, Romney said a vote for Cruz in Utah¡¯s caucus on Tuesday was the best way to prevent Trump from locking down the nomination, which would give opponents a chance to select another candidate at the party¡¯s July convention.

¡°The only way we can reach an open convention is for Senator Cruz to be successful in as many of the remaining nominating elections as possible,¡± Romney wrote.
