It’s called a Democratic blowout because the loss of a few seats in the Senate means nothing to the already minority Democrats now that they can control all legislation by virtue of holding the House. More importantly, they can now expose Trump, and that’s exactly what will happen. It won’t just be a drumbeat of anti-Trump rhetoric, it will be a fire hose of actual evidence of Trump’s fraud and criminality. He’ll still have his most hardcore base, because racism and xenophobia in America are very strong. But anyone else that sides with Trump will clearly be painted with the same excrement as Trump, softening up the Senate for the next election. Further, the Democrats can introduce wave after wave of legislation that’s overtly beneficial to middle class Trump voters who were fooled into thinking that Trump gives a rat’s ass about them. When those bills fail to advance in the Senate, everyone will see who the Republicans are who blocked them, and Trump is powerless to do anything about it. Finally, control over the House gives the Democrats a strong platform to groom and promote their next presidential candidate, who will probably be running against Pence. (And no, I do not think the Senate will convict Trump; I think there will be incontrovertible evidence of the Trump crime family’s wrongdoing, and Trump will resign in shame before the 2020 election.)
