The margins in PA, MI, and WI were quite small. We shouldn't delude ourselves. The Dems have won the popular vote in 6 out of the last 7 Presidential elections. Even unpopular and incompetent candidates like Hillary and Kerry made it very close.
Also, it's not some huge achievement she got more votes that Obama given the population is constantly expanding, so generally, recent candidates/winners will get more votes that predecessors.
Trump's total vote of 63 million broke the Rep record of 62 million set by Bush 43 in 2004, i.e., over 12 years ago. Obama's 69.5 million votes in 2008 remains the largest in history, by far. Hillary received so far 65,844,954 votes, only 74,000 votes less than Obama's 65,918,507 in 2012.
The rapidly changing demographics of this country fueled by mass immigration will make the Dems the permanent majority party. I watched over 30 years VA's transformation from a solid red state to now a solid blue mainly due to changing demographics.
If anyone had more of a justification to run and get the nomination again, it would of been he, not Hillary. Besides, he was much younger as well for a 2nd try; she will be 73!
It has nothing to do with justification. It has to do with Hillary's obsession with becoming President. She is not Al Gore who had no where the ambition Hillary has. I fully expect her to contend again for the nomination.
