The reason leftists are certain Dems will lose is because for fear of being called crass or heartless by the media and the GOP, they will think of doing something stupid like not campaign in any places Trump isn’t campaigning to make it a “fair fight,” sit on their hands and refrain from any strong attacks on Trump if the Republican commentators go “how could you?!” and maybe even officially concede defeat ahead of time like they did when Steve Scalise got shot at the congressional baseball game they were winning.
