Rove: Palin part of 'risky strategy'

One of Alaska Gov. Sarah Palin's potential presidential rivals says her abrupt resignation won't allow her to dodge scrutiny over her family.

And George W. Bush's former chief political aide says Palin's strategy is unclear, at best.

Former Arkansas Gov. Mike Huckabee said Sunday that Palin's announcement that she is resigned while still in her first term doesn't make sense in a conventional political setting.

Bush's political adviser Karl Rove says Palin has engaged in a "risky strategy."

Huckabee, who ran for president in 2008, says he isn't sure if he'll run in 2012. He does say that Palin remains a viable candidate despite her decision to quit the governor's office.

Huckabee and Rove appeared on "Fox News Sunday."
