If the Democrats lose the Senate there needs to be some serious finger pointing at the Democratic national (conservative, Third Way) leadership. If people want conservative they'll vote Republican. The conservative leadership and the Blue Dogs control the party by default. Even if the Democrats win 51 seats the Blue Dogs kill the party majority in congress because though they call themselves Democrats they vote Republican anyway.
I suggest an all out support of Bernie Sanders for president. Run as a Democrat Bernie. That's all I got because the Democratic leadership keeps recruiting consevatives.
Any other ideas?
