JEFFERSON CITY, Mo. (AP) — U.S. Sen. Claire McCaskill has reserved $3 million of TV advertising time for the final month before the November general election.

McCaskill’s campaign said Tuesday that the Democratic senator paid for the advertising in advance in order get the maximum amount of time for her money assuming that prices may rise closer to the election.

McCaskill will face the winner of an Aug. 7 Republican primary between businessman John Brunner, former state Treasurer Sarah Steelman and Congressman Todd Akin.

Brunner has been spending his own money on TV ads during the Republican primary campaign.
