Topeka ? The political action committee of the Kansas Chamber of Commerce has spent more than $394,000 on legislative races in the final days before today’s party primaries.

Campaign finance reports filed through Monday show most of the money went for mailings and radio spots for conservative Republicans running for state Senate.

The chamber’s PAC reported spending nearly $307,000 on Sunday alone, but chamber vice president Jeff Glendening said $45,000 of the spending also was listed in an earlier report.

The chamber is backing efforts by GOP conservatives to oust a dozen moderate Republican senators in primary races. But the chamber also is helping conservative candidates seeking open seats.

According to other campaign finance reports filed through Monday, political action committees backing moderate Republicans in Kansas Senate races have spent at least $178,000 in the final days before the party primaries.

A PAC for Kansas real estate agents reported spending more than $58,000 on mailings and online advertising in the week before today’s primary.

Other groups backing moderate Republicans for Senate also report spending more than $30,000 each in recent days. They include the Kansas Traditional Republican Majority PAC, the Kansas Jobs PAC and the Kansas Values PAC.

The Kansas Jobs PAC received a $15,000 contribution from the state’s largest public employees union.

Kansas allows PACs to spend unlimited amounts on ads promoting candidates if those activities aren’t coordinated with the candidates.
