When people vote they are (hopefully) not voting just for the names in the ballot, but in the political program and plans that those names presented. Otherwise no elected politician would have political legitimacy to do anything more effective than waving to the camera on TV.

The Donald Trump that people voted for is the same Donald Trump that openly said he was going to take dictatorial measures and would put Musk in charge of dismantling the government. After this no one has the right to say they didn’t know what they were voting for
