Do you want Democrats to win elections? If so, celebrating the assassination of individuals that you don’t agree with is a very bad look, and won’t earn you any votes. If you want Republicans to win, proceed. (you require independent votes to win any national election. Even if D turnout is 100%, you can’t win without independents, and a significant portion of independents are against murder; even if the target is pro 2nd amendment and anti-abortion).
