The "backlash" will be that the people that take him off the ballot may end up being murdered. Or their family might be killed. Or both. Sure, maybe it's the duty of the secretary of state in each state to remove him from the ballot. But would you be willing to do that if it was likely someone would try to murder you? And consider for a moment that it's likely that a significant number of cops that you might expect would protect you probably sympathize with political violence in favor of Trump.
Those are the stakes for the people that need to remove him from the ballot.
Are you ready and willing to fight? Because you might have to.
EDIT: People seem to think that my comment about getting ready to fight is in support of Trump. It's not. If you believe in this 250-year experiment in Democracy, you might have to be willing to fight--as in, with guns and bullets--to preserve it, and that means fighting against the Trump followers that want to end democracy for a totalitarian gov't. It happened in Germany in the 20s and 30s; don't think that it can't happen here.
We had four years of a populist far-right president that brought out the very worst in his cultists. The only reason we were (past tense) better than this was because we believed we were.
If I took an oath of office you bet your ass I’d be willing. That’s what it means to serve your country in office. If you aren’t willing to uphold your oath, resign.
I would hold no ill will to any person who resigned their position because they are unwilling but if you want to do the job, do it.
Would you though? Would you really? If you got a email of a photo of your family getting out of their car at Target or Walmart, would you really think, yeah, I'm willing to trade the life of my spouse and kids for this job? Would you be willing to do it that if you took it to the police and they just shrugged and said they didn't see anything actionable? The fact that we haven't heard of political figures being assassinated by Trump supporters yet doesn't mean that it's not going to happen; religious fanatics have blown up doctors offices and killed doctors to 'save babies', and Trump cultists literally believe he was chosen by their god to rule.
Asked and answered, it’s not going to change because you rephrased the question.

It wasn't all that long ago that people got lynched in the part of the country I live in. A candidate running against MTG--she's the next district over from me--had so many death threats and close calls that his wife divorced him and he ended up having to move out of the state to save his own life. Maybe you would be dumb and principled and do the right thing though; if so, you'd probable end up dead, esp. in a lot of the states that have really deep red pockets. Then the next person who takes the job, well, they're probably be a lot less interested in being right and dead, and more interested in being able to go home at night.
