Cardiologist Rob Steele is considering a bid for the open Senate seat in Michigan in 2014, according to a local source with direct knowledge of his interest.
Steele is best-known among Republicans for his 2010 bid against longtime Rep. John D. Dingell, D-Mich. During that campaign, Steele picked up former Alaska Republican Gov. Sarah Palin's endorsement and gave national Democrats a brief scare that Dingell could lose his safe Democratic seat. Steele lost by 17 points.

Republicans talked up Steele in 2011 when they hunted for a challenger to Democratic Sen. Debbie Stabenow. Ultimately, Steele unsuccessfully ran for a position on the University of Michigan's Board of Regents in the 2012 cycle, according to The Michigan Daily.
This cycle, both Republicans and Democrats are on the hunt for candidates to run for the Senate since Sen. Carl Levin, D-Mich., announced his retirement earlier this year.
Elsewhere in the potential GOP field, Rep. Mike Rogers continues to mull leaving his post as chairman of the House Intelligence Committee for a Senate run.
"I need to decide, is it more impactful to stay and do that as chairman, or to kind of pull out of that and run for Senate?" he told CNN's Jake Tapper on Tuesday.

Democratic contenders include Debbie Dingell, the congressman's wife, and Reps. Gary Peters and Dan Kildee.
