The House GOP’s top super PAC has reserved another $18.5 millions in ad reservations, to help Republicans maintain their slim majority.

With the new purchases from the Congressional Leadership Fund, the group has spent over $175,000,000 on advertising for this cycle. New York and California are the states with the largest new reserves. In both states, Republicans are defending districts that were won by President Joe Biden in 2020.

These reservations provide a map of the areas in which the group is most likely to see competitive races. There are only a few seats between the two groups. The breakdown of spending is as follows:

CLF will now spend money on television in two new districts, including California’s 47th open district, where Republican Scott Baugh is facing Democrat Dave Min. The group will also spend $2.3million to support Rep. Mariannette Miller Meeks (R, Iowa). CLF had not reserved time in the area before, but Democrats placed buys to counteract her. The group will also launch a digital and mail program to assist Rep. Ryan Zinke, R-Mont. ).

NYC + LA : The super-PAC will add $3.5 million to the New York City market. This includes the districts of Republican Reps. Mike Lawler and Marc Molinaro, and Democratic Rep. Pat Ryan. The group will add $2.6 million to Los Angeles. This money could help Baugh, or GOP Reps. Mike Garcia and Michelle Steel, as well as Ken Calvert. CLF has begun their purchases in both locations a week sooner than originally planned. Its combined spending is over $65 million.

Michigan: CLF will spend another $1.1million to flip Rep. Elissa slotkin’s open seat (D-Mich.). This brings its total expenditures for Republican Tom Barrett up to $8million. Slotkin is running to be a senator. The company is also contributing $180,000 to flip the retiring Rep. Dan Kildee (D-Mich. )’s seat.

The group has increased its spending on two Democrats who represent districts Donald Trump won in 2020, Reps. Mary Peltola and Jared Golden. Rep. Gabe Vasquez, D-N.M.; Jen Kiggans, R-Va.; and Zach Nunn, R-Iowa) are among the other incumbents who will see a greater investment in order to target or help them.

Republicans have raised the alarm over a huge money gap between Democrats and Republicans in the House of Representatives and Senate. The Democratic-aligned House Majority PAC, however, has reserved $215 million.

CLF must spend heavily in order to give House Republicans any chance of winning.
