Is it time to put the Paul Ryan for president chatter to bed for good?
My Politico colleague Jake Sherman reports that when Ryan says he will not seek or accept the Republican nomination at the party's convention in Cleveland this summer and he absolutely, positively, indubitably means it. Ryan does not want the nomination, does not believe a candidate not currently running could, or should, get it. And he would not take it should convention delegates turn to him in a moment of crisis after multiple ballots and implore the house speaker to mount his trusty steed and ride into the fall election as his party's standard bearer.
