You and others like you have obviously not learned a thing
The people who are lacking common sense are not conservative voters, but the GOP, their leadership, the candidates, and the strategists and consultants. Obviously they don't care about winning as they claim to. They don't listen to common sense if it is repeated to them multiple times.
It is not the responsibility of the conservative voter to unite the party. It is the responsibility of the party's leadership and of the candidates. Speaking of which, I did not see any party unity lectures when Lugar lost in Indiana, or when Ken Cuccinneli was running in Virginia. Apparently the burden is on the conservative voter to "unite".
What does the GOP and its leadership offer conservatives? Other than taking a dump on them every chance they get? Maybe they need to start earning the votes for a change.
The people who obviously don't learn a thing are the GOP leadership and their schemers. They haven't learned a thing after that last few elections.
What has Boehner's House done to put the foot down on targeting of conservative groups?
