There is no lead network news anchor more openly biased toward conservatives than Perky Katie Couric. All the viewer has to do to initially detect this bias is to observe Couric's long face and obvious frown when she interviews conservatives, and compare it to that perky smile and 'warm fuzzy feeling' that Perky Kirky appears to get while interviewing liberals. It makes me sick!
Other lead network news anchors are biased against conservatives, as well. But none are so in-your-face biased as Perky Katie Couric.
If I were Governor Palin, I would tell Perky Kirky, 'Thanks, but no thanks!', and do an interview with Greta on Fox instead. I have a bad feeling that Perky Katie Couric's video editors would butcher and slice up the interview of Sarah Palin so bad, it could make Charlie Gibson's interview look like a walk in the park!
