Florida's Rick Scott, Matt Gaetz to face primary challengers as several states head to polls Tuesday

Republicans and Democrats head to the polls Tuesday to choose their party's nominee in primary races across Florida, Wyoming and Alaska.

Republicans will keep a keen eye on the Florida primary races of Rep. Matt Gaetz, amid his feud with former House Speaker Kevin McCarthy, and Sen. Rick Scott, who hopes to lead the party in the Senate next Congress. 

Scott is expected to easily win his primary race on Tuesday against two candidates with little name recognition or financial backing.
