incumbent tries to do first is make sure they face no primary opposition because it gives them the freedom to amass a war chest and while the other party is dealing with the intraparty fight and now you have bill weld who is in the race and now the possibility of mark sanford, it seems like small challenges no doubt that donald trump will beat them both i would say, but is it enough the two of them potentially kind of picking at donald trump in a couple of key early states? making him be distracted. making him spend money. do you think that that has the potential on trump's capacity to get re-elected? >> i don't know. but the question is did bill weld encourage mark sanford to jump into the race, will sanford encourage somebody else to get into the race? you and i and everybody around the tables knows what happened in 1968. nobody expected gene mccarthy to do as well as he did, he drove lbj from the race.
