With Republican Sen.-elect John Kennedy’s triumph in the Louisiana runoff last weekend, victories by two other Republicans in Louisiana House races, and Gov. Pat McCrory’s (R) concession last week to Gov.-elect Roy Cooper (D) in North Carolina, the winners of 2016’s House, Senate, and gubernatorial races are now set. This allows us to do a little housekeeping. Kennedy’s win confirms that this is the first cycle in the history of popular Senate elections that every state that held a Senate election in a presidential cycle voted for the same party for both president and for Senate (34 for 34 this year). Also, finalizing these results permits us to give a final assessment of our down-ballot Crystal Ball projections for 2016: We picked 32 of 34 Senate races correctly, along with 10 of 12 gubernatorial races and 428/435 House races.
Looking over the down-ballot outcome, there’s one inescapable conclusion in a year that was defined by a political outsider, Donald Trump, winning the presidency: It was still a really good year to run as an incumbent in 2016, all things considered.
This election cycle, 393 of 435 House representatives, 29 of 34 senators, and five of 12 governors sought reelection (several of the governors were prohibited from seeking another term). Of those, 380 of 393 House members (97%), 27 of 29 senators (93%), and four of five governors (80%) won another term. These members of Congress and governors not only won renomination, but also won in November.See the chart at OpenSecrets
