Changing rules in the middle of the game, or moving the goalposts, to attain a desired result is wrong regardless who might do it. The Trump train has the ability to prevail with rules that have been in place since 1804. But, it requires stiff spines from Republican state legislators. As an aside, there is an interesting article on politico about another last chance strategy which may be used. I am still mulling it, but my initial reaction is that it is not viable.

If Trump does prevail, the anger of the Deep State will be so intense as to make his first term look like a walk in the park by comparison. I wouldn't put it past them to resort to assassination to prevent a second term.
