I’ll admit that two years ago I believed her to be a good pick for VP. What’s more, I still think that the choice of Sarah Palin by John McCain was an acceptable one. That said, I am definitely in the majority on this poll result.

Almost three out of five Americans believe former Alaska Gov. Sarah Palin (R) would not be an effective president, a new poll found Monday.

59 percent of U.S. adults said they don't think Palin, the 2008 Republican vice presidential candidate and potential 2012 candidate, would be an effective president of the United States.

26 percent of adults, by contrast, said they believe Palin would be effective, according to a 60 Minutes/Vanity Fair poll conducted earlier this August.

Why don’t I think she would be an effective president? Because of everything that has happened in the two years since her selection as the nominee.

The media immediately defined away much of her credibility as it adopted the narrative of Sarah Palin being some sort of country bumpkin with weird religious views. Like it or not, that image would make it hard for her to lead.

The bizarre Levi & Bristol saga has turned her family life into a soap opera.

The resignation as governor, while not unreasonable, undermined her image of toughness.

Two years of books and speeches have not served to make her appear to be more of a serious political figure.

As a result, I’d argue a Palin presidency would make the Bush years look like a time of harmony between the White House and the media – and between a GOP president and a Democrat Congress.
