(CNN) – Prominent conservative columnist Kathleen Parker, an early supporter of Republican VP candidate Sarah Palin, said Friday recent interviews have shown the Alaska governor is "out of her league" and should leave the GOP presidential ticket for the good of the party.
The criticism in Parker's Friday column is the latest in a recent string of negative assessments toward the McCain-Palin candidacy from prominent conservatives.
It was fun while it lasted," Parker writes. "Palin’s recent interviews with Charles Gibson, Sean Hannity, and now Katie Couric have all revealed an attractive, earnest, confident candidate. Who is clearly out of her league."
Palin's interview with Couric drew criticism when the Alaska governor was unable to provide an example of when John McCain had pushed for more regulation of Wall Street during his Senate career. Palin also took heat for defending her foreign policy credentials by suggesting Russian leaders enter Alaska airspace when they come to America. Palin was also criticized last week for appearing not to know what the Bush Doctrine is during an interview with Charlie Gibson.
“If BS were currency, Palin could bail out Wall Street herself," Parker also writes. "If Palin were a man, we’d all be guffawing, just as we do every time Joe Biden tickles the back of his throat with his toes. But because she’s a woman — and the first ever on a Republican presidential ticket — we are reluctant to say what is painfully true."
Parker, who praised McCain's "keen judgment" for picking Palin earlier this month and wrote the Alaska governor is a "perfect storm of God, Mom and apple pie," now says Palin should step down from the ticket.
“Only Palin can save McCain, her party, and the country she loves," Parker writes. She can bow out for personal reasons, perhaps because she wants to spend more time with her newborn. No one would criticize a mother who puts her family first. Do it for your country."
"Sarah Palin has many virtues," Brooks wrote in a recent column. "If you wanted someone to destroy a corrupt establishment, she'd be your woman. But the constructive act of governance is another matter. She has not been engaged in national issues, does not have a repertoire of historic patterns and, like President Bush, she seems to compensate for her lack of experience with brashness and excessive decisiveness."
