None of them did this because it has an absolutely awful cost v benefit ratio. In the present scenario they are likely to have a bright political future where the maximum downside is likely to be a political fizzle followed by a lucrative retirement whereas maximum downside of attempting to overthrow government is death or prison. Comparatively playing for time, doing nothing, and then voting Trump are all low risk activities which is why it is entirely believable that they should come to pass.
