TOPEKA, Kan. (AP) — Republican congressman Tim Huelskamp has filed for re-election in the 1st District of western and central Kansas and is promising to battle leaders in both political parties.

Huelskamp filed the paperwork Tuesday for a spot on the Aug. 5 primary ballot. He is seeking his third, two-year term.

The tea party congressman from Fowler has been a vocal critic of Democratic President Barack Obama over the health care overhaul and numerous other issues.

But he’s also been critical of Republican House Speaker John Boehner for not being conservative enough.

Huelskamp faces former state Rep. Kent Roth of Ellinwood and Clyde educator and farmer Alan LaPolice in the GOP primary. The Democratic candidates are Kansas State University history professor Jim Sherow and Bryan Whitney, a 2013 graduate of Wichita State University.
