A disappointing prediction

Though I would like for republican Thom Thillis to win, sadly, I think democrat Kay Hagan will win. She made a good run in getting more people to vote for her and after that Thillis could not compare to it. He had more boots on the ground and was doing more to try to get votes but Kay Hagan had more money to spend and obviously had more vote. Hagan spent almost 22 million dollars on this midterm election. She has spent on average more money than anyone else has before. Is this the reason that she keeps winning? Apparently so which is very stupid because it should not be about who spends more money, it should be about who gets more votes based on how much they are liked by the state.
