TOPEKA, Kan. (AP) _ He's been raising money for months, but Pat Roberts has finally done the one thing that guarantees he can run for re-election.
He filed for office Friday at the Kansas secretary of state's office, paying a fee of about $1,700 to make sure his name is on the ballot in the August primary and November general election.
About 30 supporters watched him sign the filing form, and Roberts pledged to promote bipartisan solutions for issues such as health care, agriculture and national defense.
The 71-year-old Roberts is seeking his third term in the Senate. His expected Democratic opponent is Greg Orman, of Olathe, a 39-year-old managing director in a private equity firm.
Roberts had about $2.7 million in campaign funds at the end of 2007.
But the Kansas Senator says he's not planning to endorse any candidate for the Republican presidential nomination.
Roberts said he will support the GOP nominee, whoever it is.
He said endorsing a candidate could require him to mend fences if another candidate gets the nomination.
Last year, Roberts made glowing comments about Arizona Sen. John McCain at a fundraiser, and McCain's campaign interpreted them as an endorsement. But Roberts has said his comments were misinterpreted.
McCain supporters planned a Friday news conference to publicize other endorsements.
Former Arkansas Governor Mike Huckabee's supporters also planned to have a Statehouse rally Friday.
Kansas Republicans hold presidential caucuses Feb. 9.
