Im confident he will help turn the houses gop agendas into enm law. Have you ever heard a less at t enthusiastic endorsement . T . Itsth hard to think of one,g but its hard to think what lls choice he had. You have the polls that show 96 of republicans are there, and either Hillary Clinton or donald trump is going to be president , bably and if youre paul ryan, evils.
