The King of Twits using MoveOn against him as a cudgel.
This is just another example of Democrats shitting on their base in order to try to attract Republican votes. Who's going to blockwalk in 100 degree temperatures for these guys -- their crossover Republican voters? Are the disaffected GOP oil company employees and indies they're trying to reach going to phonebank and work their precinct to get them elected?
Yeah, Skelly's got plenty of money. What he doesn't have much of is sense and progressive values (which doesn't differentiate him much from most of the Congress critters he's trying to join).
I would take just one Sheila Jackson Lee or Lloyd Doggett over five Nick Lampsons and Chet Edwardses. I don't know now which group Michael Skelly fits in, but the picture is starting to get a little clearer.
