No candidate is going to perfectly match your desires. So voting becomes a measurement of where your priorities lie.
Of course, media and the candidates themselves will use propaganda to manipulate your priorities.
Right-wing media has done a great job convincing people that the greatest threat to them are trans women in women's sports and illegal immigrants.
Given that the Republicans claim to be the “party of personal responsibility”, I utterly reject this attempt to frame its voters as the poor and unfortunate victims of manipulation and choose instead to hold them personally responsible.
