All eyes are back on the 41st Congressional Distict as it's one of the races that could determine which party controls Congress. 

Republican incumbent Ken Calvert is the Inland Empire's longest serving congressmember, but during the midterms, he narrowly beat his opponent, democrat and former prosecutor Will Rollins.

Now this rematch is expected to be one of the most closely watched in the country. Constituents in the district say traffic and infrastructure are top of mind as they head into the election.
