Though the post-election infighting between Sarah Palin and the McCain team has largely died down, the former Alaska governor took one more shot at her former running mate’s campaign on Thursday. In an interview with the Daily Caller, Palin said Sen. John McCain’s (R-Ariz.) camp didn’t do enough to defend her record when it came under attack. “To not have had the McCain campaign staff defend my record was an insurmountable challenge, because once a bell is rung, it’s impossible to un-ring,” Palin told the website.
