CADDO, Okla. (KTEN) — Early voting began Thursday for runoff elections in Oklahoma. 

Two Republicans — Markwayne Mullin and T.W. Shannon — are running for the unexpired term of U.S. Sen. Inhofe. Democrats Madison Horn and Jason Bollinger are vying to take on the GOP candidate in November's general election.

In Congressional District 2, Republicans Avery Frix and Josh Brecheen are competing in a hotly-contested runoff race.

Another race we will be watching is in Bryan County, where Caddo Public Schools is seeking voter approval for a  $1.3 million bond earmarked for building two new science classrooms.

If approved, the bond package will not increase property taxes for homes and businesses in the district.

The Bryan County Commissioner 1  seat is up for grabs between incumbent Ron Boyer and challenger Scott Goad.

Though all eyes are set on the general election in November, early voter Jeanie Pearcy said she believes every ballot counts.

"There's lot of good guys running, or good people running," she said. "November, of course, is most important, but I want to have a part in doing what I can."

Early voting ends on Saturday, August 20. Polls are open Thursday and Friday from 8 a.m. to 6 p.m. and on Saturday from 8 a.m. to 2 p.m.

Election Day is Tuesday, August 23.
