Total spent for the race was ~$50 million. This includes the amount spent by Republicans/Handle. Even still, this is going to be a tough loss for the Democrats to overcome. They will have to find some other way to build momentum if they want to have any chance of taking control of the House in 2018. This isn't a great win for Republicans though. They were supposed to win this race, and they wasted a lot of money and manpower on a race that wasn't supposed to be close. Interesting times we live in and the road to 2018 will be a roller coaster.
