The 2018 midterms are breaking records for being the most expensive.

According to the Center for Responsive Politics, more money has been spent on political advertising for House, Senate and governor's races this election cycle than in any other midterm election.

As of Tuesday, TV and radio ad spending was estimated to be more than $5 billion, and that number could go up.

Political action committees, or PACs, shelled out the most money, and Democrats appear to have spent slightly more than Republicans. 

Experts say a more competitive and polarized political environment is a key driver behind the uptick in spending. 

Florida takes the top spending spots for its Senate and gubernatorial contests.
