overage of the first gathering of Republican presidential candidates in New Hampshire last weekend focused on how many of them attacked Hillary Clinton, but there was another unifying message among several of the speakers: Governor is greater than senator. Govs. Scott Walker, Rick Perry, Chris Christie, and former Florida Gov. Jeb Bush will turn to fileting each other soon enough, but for the moment, these statehouse men are all making the same case. Each candidate, sometimes in nearly identical language, told the audience of activists gathered in Nashua this weekend that they should be considered for the presidency because they didn’t just talk about conservative ideas, they had put them into practice as governors.
