Agreed because if we support Romney now then we have to support him in 2016. Then what, hope for a real conservative in 2020?
Strictly stragetically speaking, not necessarily. Reagan came within a whisker of dethroning Ford, same for The Swimmer submarining Carter. But we couldn't fail, ie the Conservative would have to thump Romney in the primaries and then turn away whoever emerged from a crowded Democrat field - quite possibly a very beatable Biden.
