He is creating unity in his MAGA party. Nikki is a divider, a cheater, she destroyed the democrat party. Trump destroyed the rhino party. All that is left is MAGA. Nikki is a scam artist getting rich off of Trump haters. She is not worthy of more kindness than she has been given.
Imagine you run for office and your party is voting for their favorite. Your opponent in this same party has asked the opposing party to vote, to cheat and change their party status to vote again the rightful candidate. She needs to be hauled back to India to eat on the streets.
