Before resorting to violence, the remedy is to impeach and convict the President, and, failing that, elect a replacement President. Only if the incumbent fails to cede authority should further consideration be taken.

And, to be honest, I’m not really sure that a bunch of unorganized wingnuts that slobber all over their big-man toys are going to prevail over the National Guard, if the latter remain loyal to the President, and a lot of innocent lives will probably be lost due to militia incompetence.
