I disagree, if, the Dems take the house that's all they need to stop the Trump train in it's tracks, subpoena power will check the Dotard's freedom of having a Congress protecting his lazy, racist & fat ass. We'll finally find out what is in his tax returns, along with numerous other investigations into his administration.
The geography for taking over the senate is an uphill battle here in '18, there's little or no chance of that happening. Though, I would like to see the good guys take Florida in the senate and gubernatorial races, as well as the gubernatorial races in Wisconsin, Iowa, Nevada & Georgia.
Oh, and btw, for those that need their coffee, we got ya covered there too :
