Trump has faced four "special referendums" after he dethroned Queen Hillary. And Republicans are 4-0 in all of them. Are Trump supporters tired of winning? I don't think so. And I bet Trump haters aren't tired of losing.
It's evidence that the Democratic party doesn't have a winning message, but it's not evidence of love for Trump. Now, there's currently a battle waging over what the message of the Democratic party will be, but continuing to attack Trump is still high on that agenda, as it should be. There's a few reasons for this:
1.) Democrats are
favored by the majority of Americans to re-take the House. That's not a state-by-state poll, which is much more important in our ridiculously gerrymandered country, but it is an indicating that the winds are not blowing well for Trump.
2.) Democrats still haven't convinced anyone they have a message, and Tom Perez is a terrible leader because he won't take a stand that actually unifies the party. That needs to be resolved going forward. In a sense, 4 loses are quite noteworthy for Democrats, and may spark change (Although I'm quite skeptical).
3.) Trump's favorables are still s***, they're always been s***, and they probably will remain s*** until he leaves office. Do not brag about having exclusively approval ratings in the thirties.
4.) Despite what the DNC war machine wanted to tout, these aren't really referendums on Trump. They're referendums on Trump in areas that voted for Trump and are hardline conservative. Given that these seats polls shifted so much towards Democrats, this foreshadows a serious shift in Blue. If districts start pushing up by 10-30 points for Democrats in 2018, even if Democrats don't resolve their internal political issues, Republicans will be obliterated in the House and lose the Senate. That's obviously a serious suggestion for the districts to shift that much, but all the same, those are the shifts in the 4 districts we have just sampled. If that's the trend, then the referendum on Trump will be devastating, but it's not clear right now how much of a national shift (in the right districts) there will be. There's too many unknowns.
