Okay, let me start out by being fair to the Donald. The crowd size had a lot to do with geography. Washington DC is primarily a black city. Thus when Obama was inaugurated it was easy for his hundreds of thousands of local supporters to show up. That goes as well for the large east coast metropolitan areas. Trump’s supporters on the other hand are scattered about the American heartland — not handy to the American capital.
Now having said that, Trump is a national embarrassment brought to the White House though a confluence of bizarre anomalies. It is only fitting that a party so nasty and mean as to want to destroy the healthcare insurance of millions of poor Americans have the very foolish Donald Trump draped around its ugly neck.
