I understand exactly how the balance of power works, Trump's opponents do as well, Boss, and they will obstruct as successfully or better than did Obama's from day one. The opposition has the solid majority of the citizens behind them. Not worried anymore about alt right concerns. Neither is Trump now that he is elected.
I don't know where you get they have the solid majority of citizens behind them. That's just delusional if you followed what happened on election night. It wasn't just Trump defeating Hillary, he did so in traditional Democrat strongholds... and it wasn't just Trumps' victory, or that Republicans retained the Senate and House, they won huge statehouse races and governorships. Under Obama, Democrats have lost a ton of power... over 1,000 statehouse seats have switched. That doesn't sound like the majority of people are behind them to me.
I'm not worried about the alt-right either, they're not a majority of anything except in their own obnoxious minds. Trump is probably going to govern more as a centrist in the mold of Bill Clinton... but you have remember how wildly popular Bill Clinton was. And yes, democrats will try to obstruct Trump and they do that better than republicans... but Trump is an enigma and he doesn't like being obstructed. Plus, democrats are currently too weak to obstruct much. They're going to need to rejoin reality at some point and gain their footing again.... that's obviously not happening if fools are running around laying claim to the "vast majority" with their rhetoric.
