Washington (CNN) In politics, money frequently equals priorities, and as the midterms round the turn toward Election Day, we learn a lot by where both parties are focusing their TV ad campaigns.

Or in the case of Republicans and their allies, not focusing their ads.

A CNN analysis of data from the first eight days of October shows 16 contests considered competitive in CNN's Key Race Ratings where Republicans did not run a single television ad, either because they were no longer actively contesting the race or because they were confident in their chances.

By contrast, Democrats and their allies had only a single key race they didn't play in -- New York's 27th Congressional District, which is rated by CNN as a Likely Republican win for incumbent Rep. Chris Collins, a longtime supporter of President Donald Trump, despite his indictment for insider trading.

Nationally, each party was active in roughly the same number of congressional races -- the Democrats in 112, the Republicans in 103, according to the data. The CNN analysis used data from Kantar Media/CMAG from October 1 through October 8, the most recent currently available. The data includes ads bought by campaigns, parties and super PACs, listed by their support for Republicans or Democrats.
