BS!
More than several voters will bluntly tell the business as usual GOP that if they embrace suicide, that's fine with them. The conservative base is longer lasting and ultimately much more powerful than the "business as usual" donors. Want to make a clear distinction and a real choice? Listen to the conservative base.
Ignore them at your peril!
But that doesn't mean big donors might not take a chance on conservative primary candidates if we field good ones. That has been the strategy of the Club for Growth and the Tea Party and both have had electoral success. Iowa is an anomaly with its caucuses, which distort the whole race for weeks or months. It should be relegated to a minor run o' the mill status just because it is atypical and predicts nothing..
