Ok, D is an option. But realize that it’s much different in a congressional race with a hugely unpopular candidate (even with rank and file moderates) than in a senate race with an apparently pretty popular candidate. So, in this case, D=C in reality. I do think third party movements can work in the right circumstances, but not when it’s pretty clear that the primary voters like the alternative.
So you’re saying Scozzafava was hugely unpopular? Was that true from day one, or only after her extreme liberalism was dragged into public view? My information suggests she was doing quite well until a robust public debate ensued about her real political locus. That model still works for the (Giannoulias vs Kirk) vs (Republican X in Exile) equation.
It is not a given that Illinois’ Republican and conservative voters will support Kirk once they come to fully understand him, especially if, at the same time, they can be reassured there is a real alternative that they will be able to vote for. That’s why a broad, effective communication plan is essential to make this work. If that plan gets neutered by doubt, despair, and defeatism among those best qualified to implement it, continued failure will become a self-fulfilling prophecy.
