I see multiple threats to our nation's constitutional form of government. The right presents its own from time to time, but right now the most serious threat is in electoral "reform" sought by the left.
We do know, without question, that the losing candidate outpolled the winning one in the nation at large. In modern times this was unprecedented, but it had almost happened three times within living memory: in 1960, when J.F.K.'s plurality was barely a hundred thousand votes;

"At another point in history, I might tolerate this. As it stands, I call it treason. Did you know that in 1960 JFK lost the popular election, but won it with the Electoral College? Where were the Democrats calling for the EC's dissolution then?"
-- JFK DID win the popular vote, but only with a plurality, not a majority. He would have recieved a majority if it weren't for an electoral quirk in Alabama that cost him .4% of the vote and 6 EVs. In Alabama, the 11 Presidential Electors were directly elected. Due to the result of a state primary, five of the Democratic electors on the general election ballot were loyalists pledged to Kennedy and the remaining six were Free electors, not pledged to the Democratic national ticket. These six Unpledged electors cast their ballots for Harry Byrd (President) and Strom Thurmond (Vice President).
