This is an interesting projection. It shows the Republicans regaining control of the U.S. Senate, with all the ramifications that will bring. But it also gives North Carolina's Kay Hagan a 73 percent chance of winning re-election in what has been termed a very vulnerable seat for the first-term Democrat. Even though the Republican leadership got the candidate they wanted from the party primary — Speaker of the House Thom Tillis — the Post's analysis has Hagan hanging onto her seat.
The Washington Post graphic also give readers an opportunity to look at House races around the country. These projections should be flavored with the recognition that it is still nearly six months until the election, and a lot can happen in six months.
