For those out there loving the current Republican race but worrying that it has become somewhat orthodox in appearance and stable in candidates and support numbers, fear not: ABC News’ Jonathan Karl has the blind item for you. In the most mysterious and, for the GOP, worrisome dispatch on the Republican field in a while, Karl reports that a “prominent Republican senator” told him that the Party will not stand for a Mitt Romney loss in Michigan, and that he expects a result like that to lead the Senator to “publicly call for the party to find a new candidate,” likely former Florida Governor Jeb Bush.
