Critz: I'll never go on Fox News

Everybody who reads this site knows all about Mark Critz's union endorsements, which are a part of an attempt to appeal to an old-time Democratic constituency that's been clear ever since his 12th district congressional primary race against fellow Dem Jason Altmire started.
Now Critz is painting himself as a more reliable, traditional party member than his opponent. In an email to supporters today (posted by Keystone Politics) he refers to a recent CQ "party unity" study on voting records in which Altmire voted with Republicans 53% of the time and comments on his appearances on Fox News:
While I don’t always vote with the Democratic leadership, I am a proud Democrat and I am not afraid to say it. Jason Altmire voted with the Republican leadership 53% of the time in 2011 and never misses an opportunity to go on Fox News to bash the Democratic Party. I have never been on Fox News and I never will.
Critz voted with Republicans 31% of the time, third most in the state after Altmire and Tim Holden (33%). For comparison's sake, safe-seat Pittsburgh Dem Mike Doyle voted R 5% of the time.
Critz faces off against Altmire for the first time Sunday, for the endorsement by Allegheny County's Democratic committee.
The full letter via Keystone Politics' Jake Sternberger is after the jump:
We are making great progress in our race. We’ve picked up key endorsements – this week from the Service Employees International Union (SEIU), the Fire Fighters, United Food and Commercial Workers Local 23, the Utility Workers Union, and Amalgamated Transit Union Local 1279. The momentum is on our side. We can win this April and again in November, but I can’t do it without your help.
Sincerely,
Mark Critz
