Loki, the well goes a bit deeper than even what cyn wrote as far as Dems creating Trump (and they very much so DID)
Politics are like a pendulum the more you push one way, the more its unavoidable to push back the opposite way until everyone leaves it alone long enough to organically get to where it should be (which in politics is NEVER fyi)
Obama asked for too much too soon. And he continues to do so on his way out.
Same pendulum swinging is why BLM supporters keep shooting cops too. Its all just weight and gravity.
That is ... one of the best parodies of #THANKSOBAMA I have ever seen.
That said, Trump (or a Trump-like substance) was a necessary result of the GOP's policies and practices. Simply put, they have engaged in anti-elite, anti-establishment rhetoric, so it should come as no surprise that the elite and the establishment were not able to seize control. They have continuously stoked the fires against politicians, so, again, is it any surprise that a non-politician has seized the levers of power? They tried to harness the fury of nativists and racists, without fully comprehending that these same people might not be as attached to free trade as the GOP is.* They fed off of the anger and resentment of talk radio and Fox News, which allowed short-term electoral success at the expense of long-term electoral stability. And so on.
More importantly, politics is hard. It is the art of the possible, filled with compromise and gradual change. It is not the continual unmet promises of revolution unfilled, with brinkmanship as its lodestone ("We'll repeal Obamacare, and shutdown the government, again, to do so."). Trump only exploited that which was already there.
The Democrats have 99 problems, but the Trump ain't one.
*This is not, by the way, to say that the GOP is/was nativist and/or racist. But it was perfectly happy to pander to those interests to get their votes.
