A new poll suggests former Vice Presidential candidate Sarah Palin is losing credibility among voters.

An ABC-Washington Post poll finds 55 percent of Americans have an unfavorable view of Palin - an all time high. Seventy-seven percent think she is not qualified to be president.

The poll shows Palin is even losing support in her own party. Fifty-two percent of Republicans think she's unqualified for the White House.

This could be bad news for Palin who has not ruled out a Presidential run in 2012.

In the next few months, she's keeping a full schedule of public events: campaigning for Sen. John McCain, headlining a Tea Party rally, and even speaking at the Daytona 500 Nascar race.
