I received this e-mail from the Howard Dean campaign this morning:

Dear Arlo,

The entire race has come down to this: we must win Wisconsin.

We must launch our new television advertisement on Monday in the major markets in Wisconsin. To do that, I need your help to raise $700,000 by Sunday. Please contribute $200 today so that we can reserve the air time:

We will get a boost this weekend in Washington, Michigan and Maine, but our true test will be the Wisconsin primary. A win there will carry us to the big states of March 2-and narrow the field to two candidates. Anything less will put us out of this race.

All that you have worked for these past months is on the line on a single day, in a single state. We have come so far to change our political process and restore our democracy-we can't stop now. Your $200 contribution will allow us to get out our message onto the airwaves, and win Wisconsin. Please contribute now:

Thank you,

Governor Howard Dean, M.D.

Yeah, they're in trouble.

Is it even possible for Dean to win my neighbor to the north, though? I can't find any tracking polls for Wisconsin (and if you find one, please tell me), but a win could give him a little boost going into California.

A statement like this e-mail, however, just adds to the defeat many Dean supporters must feel.

In other presidential politics speculation, interesting potential running mate buzz: Bill Richardson.
