The protests over Trump's nominee (which became Kavanaugh) were in high gear even before a nominee was named. Many Democrats have not been shy about saying that their goal is to oppose Trump at every turn, and they have. One even encouraged supporters to harass members of the Trump admin if they came across them in public, and they have. There is ample reason to believe that if congress flips we will be facing a two year stalemate. It's seems crazy to me that people are disputing that. How many Dem votes have their been for legislation supported by Trump since he took office. Not very many at all, I'm certain.
