John Lewis, the former state director for Sen. Max Baucus (D-Mont.), has filed paperwork to run for the state's only House seat.
On Aug. 16, Lewis filed a "statement of organization" form with the Federal Election Commission. The form is required to register new campaign committees.
Lewis had also been viewed as potential candidate for the seat being vacated by Baucus, who is retiring. Several Democrats have passed on the Senate contest, leaving the party searching for a candidate.
On the Republican side, Rep. Steve Daines is considering a Senate run, a possibility Lewis is no doubt watching, since Daines's decision means the difference between an open seat House race and a campaign against the incumbent.
Lewis stepped down as state director for Baucus earlier this month to explore his next move.
