So, if the Administration is still filing lawsuits and the President still insists he will win, can Republicans be blamed for believing them, and eagerly looking forward to victory?

Yes. Yes they can.

For heaven’s sake, Donald Trump has been president for four years now, and the dominant figure of American politics for five. It should be rather obvious by now how he works. The president’s 2017 transition was so bungled that it took him until approximately now just to staff his administration with people who agreed with him. In 2020, the President spent all year claiming mail-in voting was a fraud vehicle, but waited until Election Night to have his son-in-law-in-chief go casting about for a lawyer. ‘Trust the plan’ does not work, because there is no plan. And the longer Trump’s supporters continue waiting for his miraculous triumph, the longer it will take them to begin the much more difficult task of moving past him.
