The fact is:
in 2016 Hillary Clinton ran a campaign for Republicans. She ran on the right, appeasing cracker suburbanites, the Never Trump movement, nationalists, Nat Sec ghouls, corporate power, etc, and lost to Trump.
In 2020, Joe Biden ran on end the forever wars, reign in police violence, dismantled the migrant carceral system, and punishing nazis. He got 81 million votes; nobody has ever gotten more to this day.
Which campaign did Harris run?
I rest my case.
