Bullock will probably run against Daines in 2020.
He'll be lucky to get reelected next year, he stands no chance of defeating Daines in 2020.
Back to the topic, this race is likely R. Republicans need to run strong campaigns if they want to win in a purple state like Montana, but all things considered I think Zinke should be fine (especially since this is the House district and not a Senate race).
Bullock will win reelection, but Dems strongly are favored in Senate races in presidential years. Is it important as def Ernst or Gardner or Tillis no. But, Sullivan or Daines will have competition.
