Only two or three prospective GOP presidential candidates are qualified for the job, says Iowa Republican Sen. Chuck Grassley. From Ric Hanson at Radio Iowa:

Iowa Senator Chuck Grassley says it's still too early for him to pick a favorite among the many possible presidential candidates making the rounds in Iowa. Grassley, a Republican, says he first needs to know where the candidates stand on the various issues, though he says, "only two or three of them are qualified to be president."

Grassley says he'd try to determine if the candidates who could win the Iowa Caucuses could also go on and had the resources to win in states like New Hampshire, Florida, Nevada and South Carolina. He says, "It wouldn't do me much good to back somebody that won in Iowa if they can't carry on the campaign elsewhere."

It's unclear which "two or three" Grassley is talking about, but Hanson quotes him expressing surprise that Sarah Palin traveled to Israel, signaling she's perhaps serious about a bid.

Almost every potentially serious candidate has made multiple trips to Iowa in the past year. Mitt Romney seems to be the only notable contender not showing too much interest in the Hawkeye State these days.

Grassley has been in the Senate since 1981 and, like other Senate veterans, generally isn't afraid to speak his mind.
