Topeka ? Anticipating a last-minute blitz by single-issue, special interest groups before Tuesday’s primary, Kansas Republican Party Chairman Dennis Jones urged GOP voters to disregard the attacks.

“Kansas elections are not for sale,” Jones said. “The Republican Party of Kansas represents the public interest, not special interests. We won’t be hijacked.”

Jones didn’t reveal what groups he was talking about but referred to newspaper reports about organizations that have vowed to help conservative Republicans.

Some of the groups are anti-tax and have targeted state lawmakers who supported tax increases for schools; some of the groups are anti-abortion and have targeted abortion-rights supporters; and some are targeting lawmakers who opposed a proposed constitutional amendment to ban same-sex marriage.

There are a handful of hotly contested legislative races between so-called moderate and conservative Republicans.

“We all get their junk mail and we all hear their radio ads,” Jones said. “The people know that these special interests and single-issue advocacy groups distort and misrepresent the truth.”

Tamara Cooper, executive director of the conservative Kansas Republican Assembly, dismissed Jones’ comments.

“He is wrong. The people of Kansas know their candidates and are going to vote intelligently,” Cooper said. “All the candidates will be working hard this weekend,” she said.
