If the democrats believe one thing; they should believe this. Their heads are on the chopping block. Surprisingly not by the voters; but by Obama himself. He has already started by not allowing Republicans to participate. Ask yourselves democratic Congress people; What makes you think that you will not be the next ones excluded? It will happen if you allow Obama to take over. He is well on his way to doing you in.
More and more I've been thinking about the French Revolution. The Jacobins wanted to bring the king down, and they did, but then found that governing was difficult. Pretty soon the Jacobins were struggling amongst themselves, with the most radical people rising to the top -- portraying themselves as champions of the poor and down-trodden. Once these folks had power they started the Reign of Terror, killing those revolutionaries were not sufficiently extremist (as well as a great many members of the clergy). In the end, this did not work out well.
