You can sort of understand and tolerate it when the GOP leadership says nothing about Trump’s frivolous election-related lawsuits, because the litigation won’t change the outcome of the election, and court battles are as American as apple pie. Attempts to persuade state officials to ignore state law and refuse to certify totally lawful results, however, are in a completely different category. They are an attempt to subvert the system, not to work within it to the bitter end.
Trump is going to do what he always does, but any GOP leader who acquiesces to this kind of behavior is marking himself as an enemy of liberal democracy in this country, and should expect consequences.
