Mo. Republicans in close race for US Senate

JEFFERSON CITY, Mo. (AP) -- Three Republicans who touted their conservative credentials are in a close Missouri primary for the right to challenge Democratic U.S. Sen. Claire McCaskill.

Congressman Todd Akin, former state Treasurer Sarah Steelman and businessman John Brunner all were receiving a good share of support from Republicans.

Akin had more than a third of the vote, with two-thirds of the precincts reporting. Brunner and Steelman each had less than one-third of the vote.

All three Republicans have emphasized McCaskill's ties to President Barack Obama and have vowed to try to repeal the federal health care law.
