One of my goals is to help diffuse the Democratic obsession with electability, which I believe is extremely damaging to the party around the country. It makes Democrats appear pandering (we will say or do anything in order to get elected), shiftless (we don't stand for anything except getting elected), out of touch (our ideas aren't good enough to get us elected--we have to change and move toward Republicans in order to achieve office) and dishonest (we can trick people into voting for someone based on his or her resume / demographic profile). In short, in the effort to make one Democrat look good, playing the electability card makes the whole party look bad, and more interested in power for the sake of power than power in order to do actual good.

You've now placed their voice above yours. If you are going to do that, why not just let them tell you who to vote for directly? It would take the guessing out of it.
