Yes, I think many here are missing the strategic aspect of the post and believe someone is advocating they have to give up their values. No one is advocating that.
The Dems have been running on "we hate Bush" for so long they forgot that they really don't agree amongst themselves all that much.
Rahm went out and recruited a bunch of vaguely conservative sounding Dems, and the strategy got them elected. They were not forthright about who they were and look where they are now. It is possible that what they thought was a winning strategy to get a bunch of Dems elected may ultimately result in a long term shift away from the party.
All the "pro-life Dems" have been exposed as frauds, and the voters are angry because of it.
Be who you are, and say who you are.
