Jack Cafferty nails it.

Jack Cafferty is a grumpy old man.

Grumpy old men tend to really side with the Republicans more than the Democrats, from what I’ve seen.

However, Cafferty has some comments about Sarah Palin’s performance in her recent interview with Katie Couric, and I think he nails it.

Apparently, there’s also some nervous feelings within the Republican world that McCain made a bad choice. This from Politico:

A growing number of Republicans are expressing concern about Sarah Palin’s uneven — and sometimes downright awkward — performances in her limited media appearances.

Conservative columnists Kathleen Parker, a former Palin supporter, says the vice presidential nominee should step aside. Kathryn Jean Lopez, writing on the conservative National Review, says “that’s not a crazy suggestion” and that “something’s gotta change.”

Tony Fabrizio, a GOP strategist, says Palin’s recent CBS appearance isn’t disqualifying but is certainly alarming. “You can’t continue to have interviews like that and not take on water.”

“I have not been blown away by the interviews from her, but at the same time I haven’t come away from them thinking she doesn’t know s–t,” said Chris Lacivita, a GOP strategist. “But she ain’t Dick Cheney, nor Joe Biden and definitely not Hillary Clinton.”

This VP debate Thursday night should be interesting.
