Obama played a role in nudging things
Making a phone call or two is not the same thing as dictating how millions of people vote. There is no way that millions of people changed their votes because of anything Obama did. But yes, pretending there was an Evil Mastermind pulling the strings and controlling the votes of millions sounds a lot more exciting then the boring reality that a majority of voters, for whatever reason, did not understand how great of a politician Bernie Sanders is.
I don't know how you got that from "Everybody deserves to have their own rhetoric used against them." I have learned that when people use terrible rhetoric to bully others it is best to throw it right back in their faces. I'm never going to tell Nikki Haley to "go back to India". But an asshole like Retarded Musk? Hell yeah.
