DonDiego loathes Hillary because she is a woman. The nerve of the inferior sex trying to assume power! Much of the irrational hatred directed at her stems from that sense of outrage.
Hillary is absolutely correct in a broad sense. The Russians are going to interfere in the 2020 election. And their efforts will be directed toward making Trump the winner--as in 2016.
So while DonDiego does not feel the shame that he should, he should know that a vote for Trump is/was a vote for Russia. Russia wanted Trump to win and devoted massive efforts to make sure that would happen. Anybody who voted for Trump abetted those efforts. That is indeed shameful--and unpatriotic.
The reason why a third-party candidate would hurt Trump more than his eventual opponent is that millions of Republicans feel shame and disgust for having voted for Trump and need a place to run to. A Democratic third party candidate would be on the outer fringes and wouldn't have any real effect. But a Republican third-party candidate could easily siphon off millions of votes from Trump.
