So which party is it that is supposed to be in the midst of a civil war?

MoveOn.org is sending out emails today seeking more contributions for its campaign to defeat any Democratic senator who does not fully support Obamacare. Yesterday the left-wing activist group asked members to contribute “to a primary challenge against any Democratic senator who helps Republicans block an up-or-down vote on health care reform.” Today, MoveOn reports that it has received $2 million in pledges in less than 24 hours. “It’s a clear sign of how angry progressives would be at any Democrat who helps filibuster reform,” MoveOn executive director Justin Ruben writes in the new email.

“The larger the war chest we can offer a potential challenger, the stronger the signal we’ll send to conservative Democrats,” Ruben continues. “So we’re setting a huge new goal: $3 million in total pledges by the end of the week. That’s plenty to launch a serious primary challenge.”

MoveOn is already planning radio ads targeting Louisiana Democratic Sen. Mary Landrieu and Arkansas Democratic Sen. Blanche Lincoln over the health care issue.

The bottom line is that in spite of the over-heated rhetoric, these sorts of dust-ups are all part and parcel of “Politics as Usual”. It is impossible to get hundreds of thousands of adults to agree on everything. There are going to be disagreements. When you consider the stakes involved, it should surprise no one when things get ugly upon occasion.
