Pro-life voters now have another choice for president — and a Catholic, at that. But, given his track record, on a hunch, I’d say his chances are slim-to-none.

It’s Alan Keyes:

Alan Keyes, a Marylander who ran unsuccessfully for the GOP presidential nomination in 1996 and 2000, has formally entered the 2008 White House campaign.

Keyes, 56, announced on his Web site, RenewAmerica, he filed his candidacy Friday with the Federal Election Commission.

He told radio talk show host Janet Parshall he was unmoved by what he called the lack of moral courage the other candidates had demonstrated.

“The one thing I’ve always been called to do is to raise the standard … of our allegiance to God and his authority that has been the foundation stone of our nation’s life,” said Keyes.

Keyes, who held several positions in the U.S. State Department during the Reagan administration, ran for the U.S. Senate from Maryland in 1998 and 1992.

During the 1996 campaign for the Republican presidential nomination, he was briefly detained by police in Atlanta after trying to force his way into a candidates’ debate without an invitation.

Illinois Republicans recruited him in 2004 to run against the Democratic candidate — and eventual winner — Barack Obama for a vacant U.S. Senate seat.

Keyes accused Obama during the campaign of taking the wicked and evil position on issues like abortion.

He may make the GOP debates a little livelier. But that’s about it. To my knowledge, Keyes has a perfect track record of having never won an election for anything, anywhere. Given the way the primaries are being front-loaded, this could be a short candidacy. Very short.
