I don't know about the Maine seat, but Morris' observations are as of today. When the banks start foreclosing on deadbeats that were saved by the moratorium on foreclosures (thus derailing the "recovery"), or the Loony Left does its level best to make the OWS shit from last year into this year's riots, the Dems are going to have a big problem.
Coupled with what Dingy Harry Reid did last year to cut off the Senate Republicans' amendments to some bill that the Dems were trying to choke through (he said that cloture wasn't needed, thus destroying the filibuster forever), and Obamacare will be repealled.
