The Democrats have been playing lots of tricks lately to stack the deck in favor of their healthcare plans at townhalls.Alan Grayson and others waited until the last minute to schedule theirs. Some, like Grayson, then had them in union halls to ensure sympathetic audiences.But Martin Heinrich may have pulled the best trick yet.His townhall meeting is advertised as starting at 3:00 p.m on August 22nd. That’s on his website. If you call his office, they’ll tell you the same thing.But Heinrich also sent out a mail piece in the district. I’m told it went only to registered Democrats.That mail piece, which you can see here, says the townhall starts at 2:30 p.m. It looks like Heinrich decided to give the Democrats in his district a head start.
