CLEARWATER, Fla. - With less than 24 hours until the filing deadline, Florida state Rep. Kathleen Peters submitted papers Monday to run in a Republican primary for the late Rep. C.W. Bill Young's (R-Fla.) congressional seat.

Peters, who served as the mayor of South Pasadena before her election to the State House in 2012, will face off against former Young staffer David Jolly in the Jan. 14 primary. Jolly, a former counsel for Young, has been endorsed by Young's widow, Beverly.

A contentious primary could harm Republican chances of holding the seat, which is considered to be a toss-up. The race could be a bellwether for the 2014 elections.

While Young won the seat by wide margins, the district voted for President Obama in 2008 and in 2012.

The winner of the primary will have only a few months to pivot to the March 11 general election campaign against Democrat Alex Sink.
