Outside spending groups, super PACs report spending $2.7 million in Nevada’s U.S. Senate race in past week.

Outside spending groups and super PACs have reported spending $2.7 million in Nevada’s U.S. Senate race in the past week.

The spending this early in August suggests that this will be a big spending month, with millions more dollars to be poured into the nationally watched race for the open seat of retiring U.S. Senate Minority Leader Harry Reid, D-Nev.

U.S. Rep. Joe Heck, R-Nev., is running on the GOP ticket against Democratic candidate Catherine Cortez Masto, a former Nevada attorney general. Super PACs are political action committees that spend for and against candidates independently of those candidates’ campaigns.

Here’s a look at who’s spending the money, and where it’s going, according to Federal Election Commission filings as of Friday:

• The American Federation of State, County & Municipal Employees political action fund reported spending $870,836 on television ad production and an ad buy for ads targeting Heck.

• Americans For Prosperity, a conservative group with ties to billionaire brothers David and Charles Koch, reported spending $6,901 on door hangers and phone calls to voters, all of it opposing Cortez Masto.

• Freedom Partners Action Fund reported spending $596,935.33 on digital and television ads and production opposing Cortez Masto.

• Immigrant Voters Win PAC, funded by billionaire George Soros, reported spending $53,326.95 on canvassing voters and literature in support of Cortez Masto.

• John Bolton Super PAC spent $350,000 on a media supporting Heck.

• Majority Forward spent $251,480.40 television production and advertising opposing Heck.

• The National Republican Senatorial Committee put $469,185 toward ads opposing Cortez Masto.

• Planned Parenthood Votes, a pro-choice organization, put $119,213.24 into phone calls and voter canvassing, all of it supporting Cortez Masto or opposing Heck.
