Frankly, I don’t feel passionately towards one or the other. Either one would probably be roughly the same, although Tiahrt might be marginally better (although Moran scored as the most Conservative from KS last year). According to Kabar, Tiahrt has improved his record on immigration, but Brownback’s is terrible. I’d prefer NOT to see Brownback as Governor, because I suspect he may try to use that as a springboard for the Presidency (just in time as his voting record has worsened into mushy “moderate” territory, and he clearly suffers from Potomac Fever). Since the Dems have no viable candidates, I wouldn’t mind seeing Tiahrt switch to the Gov’s race and knock out Brownback. KS has a real problem with illegals, and I have a sneaking suspicion that Brownback won’t do squat about it.
Looks like a case can be made for either over the other.
