Miller appeared on Fox News on Sunday, where he went off on a rant about the Democratic votes were thrown away as the party rallies around Vice President Kamala Harris.
"They held a primary. They had ballots. They filled out circles!" Miller shouted on Fox News. "They went to the voting booths. They spent money on advertisements!"
Still yelling, Miller says that Republicans also spent money running against Biden.
He didn't really promise per se. He said in some interviews that he saw himself as a bridge candidate, but he never made a pledge. I assume he was trying to not make himself a lame duck president right out of the gate, which can make it difficult to pass policies.
