OK, so the most poignant thing you have is from OVER 3yrs ago. Wow, impressive. That's like siting Centro's 2mi PR from him Frosh yr and saying he has no shot at winning NON. Nice work - anything maybe in the last 12mo, anything?
As for Maher, let's just look at the (2) most recent episodes from his site - notice I could go digging further, but lets look at the last few weeks and you tell me if this sways more to the Left or Right:
May 18
Dem Harold Ford Jr (LEFT)
Sean Penn (so far LEFT he should count 2x)
Garry Shandling (borderline, but no doubt still LEFT)
Sanjay Gupta (I'll leave him as neutral - served under Hillary & Bush)
April 27
Jamie Tarabay (reporter for NPR - doesn't get much further LEFT)
Lisa Schiffren (I'll leave her as neutral despite her stance on gay marriage)
Dennis Kucinich (LEFT)
David Iglesias (2yrs ago right, I'm not so sure he's a huge fan of the Bush administration esp after the events of the previous 9mo, but I'll leave him as neutral as my gift to you)
So, just looking at the last 8 guests, we have:
Left/FAR LEFT: 5
Neutral: 3
Right: ZERO
So if we have a panel and include Maher, we have 6 panelists whom are Left or FAR FAR LEFT, 3 who are neutral and NONE which are Right. You're telling me that's even??
