A judge will hear arguments today in a challenge to Republican Vern Buchanan's slim victory in the 13th Congressional District race.

State officials certified yesterday that Buchanan won the House seat being vacated by Republican Representative Katherine Harris.

But his opponent - Democrat Christine Jennings - is suing because she says voting machines malfunctioned in Sarasota County. Jennings says she won’t quit until all the votes are counted…

“I am committed to seeing that the will of the voters is carried out in this election of 2006. I will not rest until the intended votes are counted and every person’s vote is counted and reflected accurately.”

Jennings' lawsuit says more than 17-thousand Sarasota County voters who cast ballots in other races November seventh failed to vote in the congressional contest.

That’s nearly six times higher than in the other 13th District counties or on Sarasota's paper absentee ballots.

Buchanan says the people have spoken and he's won the election.
