You don't have to be happy with the results to accept the results of an election.  I was far less than happy when George w. Bush was elected in 2000.  However, I respected the actions of Al Gore in accepting the decision of the US Supreme Court which awarded the election to Bush.  Like in sports or poker,...sometimes you win, sometimes you lose.  To refuse to accept the validity of a presidential election is unprecedented and challenges the backbone of democracy.

Trump is not addressing his dislike of Ms Clinton with his action.  He's challenging the PROCESS which will (almost surely) elect her.  That process is so decentralized and so "accountable" that the "global conspiracy" Mr Trump posits is impossible.  IMO, Trump has determined his ego is more important than the welfare of our country.  That bothers me very much.
