Of course he's energized the deplorables. The KKK, the bigots, the extreme right, and the Russians all endorsed him. In normal times, doing or saying 1/10th of what Trump's behavior would have been more than enough to disqualify any serious candidate. So, yeah, it matters how he got to the presidency. We shouldn't normalize his deplorable behavior simply because he managed to win the White House.
I'm not saying all Trump voters are deplorables. Many mean well, are decent people; they're just misguided as to their assessment of and expectations from DJT.
Imagine how he would be behaving today, same with the Repubs and several of members here, if HRC won because she had asked the Russians to find and release Trump's emails, and his tax records, while the FBI director announced the week before the election that he has found damning evidence of Trump University, his ties to Russia, tax evasion, etc.
For all her faults, we knew how bad HRC was. And, the worst was a mudslinging campaign for 30 years, with the help of Russians in the last 2 years. But, I fear we do not know the worst of Trump. If this is cause for celebration, then more people should have shown for DJT inauguration.
