This conflict on the RPF today is because Romney is campaigning in Maine tomorrow, Paul is in Texas resting right now. (allegedly)
I must say as long as Paul arrives by Friday night and can be ready to work it on Saturday, this shouldn't be the end of the world. For example, 1 caucus occurs Friday, one. And in 2008 it got about 10 votes cast, we got 1 vote there. So missing that contest is far from devastating. Even today, 3 caucuses and yet the votes cast in 2008 total about 80 votes for the three, so again (hopefully) not critical.
However Saturday's voting will likely cast 1,000 votes, possibly more. Making it some 20%+ (ballpark) of the votes cast in the state. Saturday is a can't miss day if you have any hope to win Maine.
So folks, myself included, are being critcal of Paul not being in Maine directly from Minnesota, mostly because it doesn't sound like it's enough of a priority with the campaign.
