Mixed martial artist Pat Miletich says he is considering a bid for the U.S. Senate.

Miletich, a former UFC champion from Bettendorf, tweeted last week that people could pencil his name in next year for Senate, adding “Bruce Braley cannot win that seat.”

Braley, a Democrat from Waterloo, has said he is running for the seat being vacated by Sen. Tom Harkin, D-Iowa.

Miletich now appears on Showtime, ESPN and AXS.TV as a commentator. He also has co-founded a company called Fire Horse Combatives, which trains law enforcement and military members.

In an interview Monday, he said he hasn’t decided whether he will add “Senate candidate” to his resume but he has been thinking about politics for a couple of years.

"A lot of people are fed up with a lot of things that are happening in the country,” he said.

He criticized the influence of special interest, and said he believes in term limits. He also said the government is intruding too much on the private sector and individual rights.

“I’m not a fan of the left, socialist mentality at all,” he said.

Miletich is a registered Republican but said it was possible he could run as an independent.

The 47-year-old also left open the possibility he might even run for a local office, such as mayor of Bettendorf. But then he added, “I never think small.”

Harkin, who has been in the Senate since 1985, said in January that he would not seek another six-year term. That has set up a scramble to see who might succeed him. Rep. Steve King, R-Iowa, as well as Lt. Gov. Kim Reynolds and state Secretary of Agriculture Bill Northey, both Republicans, also are considering runs.
