Trump's temper tantrum worked and he has succeeded in completely blowing everything up. Divided government is a better government. One party controlling on either side is not good, especially when there is such divisiveness and spitefulness.
This part is true ONLY when one of the two sides is NOT a bunch of seditious lunatics. If the "right" was the "right" from before "southern strategy", you would of course be 100% correct!
Context is important in the *real* world! We don't live in your make-believe world.
Trumps and the group that backed his nonsense, especially in since the election, definitely fall into that category, but bc the house was democrat controlled it was better than it could have been. It is always better when divided, forces compromise or nothing. A free for all of cutting taxes, raising taxes, cutting regulations, increasing regulations, etc unfettered is not good, and for the democrats all it means is that one or more will turn over again in 2-4 years like it has for both parties in modern history.
I don't know where you live. If you get a chance, someday please visit the original America where American dream still lives. I live in a New England town where republicans did not field a candidate in most local races last time around. The "all-D" local government, FYI, has just announced our taxes would be lower next year. I don't plan on specifying which town it is (because I like to stay anonymous online). However, you can also google up some towns in MA (yes, that Commie hell-hole state), where I have some friends, and where the "R"s have not fielded candidates for a few decades. They are paragons of well run, fiscally disciplined local governments with some of the highest ranked schools in the country and all other parameters of HDI that you can think of.
"Compromise" does not work with ideology. You can not "compromise" with Joseph Stalin or Ayn Rand, or Ayn Rand's protégés that control the "establishment wing" of the republican party for that matter. It worked when Eisenhower implemented New Deal policies faithfully that he personally disagreed with!
The best outcome for America would be if the "establishment" (maybe 1/3rd of republicans today) and the "trumpists" (maybe 2/3rd) split. This establishment (I call this the "Charles Murrey" wing) is the real culprit for where we are today (look up when they ascended = Regan presidency and the divergence Human Development Index indicators in the US compared to other OECD). The majority of the working class trump voters do not strike me as malicious or ideological, and once their real issues (caused by the "Establishment" wing of the same party) are resolved, I am hopeful they will turn things around.
