Steve:  if you are going to opine, you owe it to your readers to describe the facts accurately.
1). There is another way to amend the Constitution that bypasses Congress.  Unlikely? Maybe.  But perhaps it would be more likely to succeed than going through Congress.
2).  Trump hasn't been elected by the Electoral College yet.  That won't happen until the 19th.  Don't get ahead of yourself.
3) The Constitution makes no provision for a popular vote for President.  If you don't believe me, I invite you to read the document for yourself. Article 2 Section 1 (as modified by the 12th Amendment) is a good place to start.  You will note the part about Electors being chosen by the state legislatures.   No popular election is required.  I'll bet that most who read this don't know this simple fact.  
Perhaps if more people would take an hour to actually read the document...and insist it be followed...we would all enjoy better governance.  What say you?
