That's what it looks like. (Scroll down to the sixth item.)
As Mark Murray points out, this isn't exactly a shock.
But it is more evidence that Collins' re-election is seen as vital by members of the pro-escalation caucus. And they're right.
After all, Collins has endorsed the escalation's biggest Republican supporter for President--why should't she be endorsed by its only non-Republican supporter?
Heck, Sen. Lieberman (CFL-CT) isn't even waiting to see who her Democratic opponent turns out to be before endorsing.
Maybe because he knows that no matter who she faces, Collins will be a more reliable vote for the pro-war agenda than her Democratic opponent.
In other words more out of state money!
