convention in july in cleveland and this is how it would work. the delegates become unbound on later voting and they can vote for other candidates or they could vote for somebody else and that's what there's a lot of talk on thursday riding in on his ride horse to save the party. >> well, a source close to romney says romney is definitely not running for president but he just wants to make a difference by making the case against trump. well, also at last night's debate marco rubio slammed democrats for politicizing the water crisis in flint, michigan. >> rubio backed michigan's republican governor rick snyder who hired lawyers at state expense to assist with civil representation in the case. the residents of flint got some help from the federal government yesterday through expanded medicaid coverage but a $200 million aid package is stuck in the senate because of procedural issues. and hillary clinton was keeping a close eye on the debate and having fun at the expense of the republicans.
