ST. PAUL, Minn. (AP) — Republican U.S. Rep. Chip Cravaack says there’s little difference between the three Democrats competing to challenge him in one of the country’s battlegrounds for control of Congress.

Cravaack filed paperwork to run for re-election on Wednesday in St. Paul.

He is a top target for Democrats after upsetting former Rep. Jim Oberstar two years ago in a northeastern Minnesota House district that had long been considered safely Democratic.

Cravaack says Democrats Rick Nolan, Tarryl Clark and Jeff Anderson all represent “more taxes, bigger government, more regulation.”

He says he won’t engage in the campaign until after their Aug. 14 primary, but already has doubled his campaign team from last time and aims to raise “as much as I can” to fund his re-election effort.
