Glad the Dems got the House, but looks like we lost ground in the Senate. Killer to lose Missouri, Florida, North Dakota, and it appears Montana as well. We did pick up Nevada, but losing 4 to gain 1 doesn't seem like a great bargain. We can bottle Trump up in the House, which I great... but where we have potentially more Supreme Court openings depending on the health/status of Ruth Bader Ginsberg and Stephen Breyer(both in their 80s) and where federal judiciary appointments will surely continue coming up that boosts Republican hopes at chipping away vital protections and rights. As well, impeachment is tried in the Senate... even if the House Dems move to force Donald Trump to face impeachment, the Senate will be controlled by a Republican Party even more beholden to Trump thanks to their ability to stave off the Democrats. Especially with Texas(so close to being a purple state, but no cigar just yet with Beto O'Rourke's narrow loss to incumbent GOP Senator Ted Cruz), losing Claire Mc Caskill in Missouri, Bill Nelson in Florida, Joe Donnelly in Indiana(then again, for the GOP why have a faux Democrat when you can put in a real ultraconservative Republican), Jon Tester in Montana and Heidi Heitkamp in North Dakota... we just flipped Nevada..so where are we now? 54-46 Republican?  Until we control the White House and both houses of Congress, we'll get nothing done. Even if we evict Donald Trump in 2020(and if we do, I doubt he'd concede the results and would rather spark the bitterest constitutional crisis yet) unless we have the Senate we'll get next to nothing through with a more solidly hard right Senate and I believe we face a similar situation in 2020 in terms of defending more seats than the GOP.
Don't forget, two prominent critics of Donald Trump in the Senate... Bob Corker of Tennessee and Jeff Flake of Arizona, decided to run rather than fight Trump within the party and that John Mc Cain, Trump's real opponent among GOP party leadership, is dead and gone to have been replaced by always reliably ultraconservative Jon Kyl. Their replacements, most infamously Tennessee representative Martha Blackburn, as well as in other states the GOP flipped, are reliably on the far right. Moderate Claire Mc Caskill tried to run away from more progressive Senators(particularly Bernie Sanders and Elizabeth Warren)and was replaced by a virulent conservative, Josh Hawley. Moderate liberal Bill Nelson was edged out in a stunningly tight race by reliable conservative Florida governor, Rick Scott. As great a night it was in the House, the Senate losses sting badly. We lost ground, and picking up the House isn't enough of a boost to feel particularly cheerful this morning about.
