If revenge was important to Trump, Hillary Clinton would be in prison for paying for a lying Russian dossier to try to tank his election...Correct. The only reason Trump berates her is revenge for her to dare challenge him.
For his election he is better off moving on to Biden. Revenge and hate are more important to him.
If she completely capiulates and vows to support him, she will be allowed back in, but not until she does some serious ass kissing.
