I could see Murphy winning over Rubio. Rubio will be seen as an opportunist.
Murphy will win this election and it won’t be that close. Murphy was a Republican until 2008 and is just “moderate” enough to pull Republican and Independent votes from Rubio. Of course it’s all a sham since Murphy will vote for Harry Reid as Majority Leader, but Rubio will lose handily. If Rubio ekes out a win it is because Trump has coattails.
