Have Republicans really abandoned democracy and decency in favor of keeping themselves in power ?

Not at all, considering the acts that Democrats are pulling, the tricks they are  taking to avoid allowing The "Voter Fraud" cases making it to trial.

Not allowing or avoiding arrest for Perjury is one way to keep going to court out of the question.

Remember the First day and wintin 100 days promise of the Biden and Crew.

Yes but it's not surprising since they've been pushing that agenda for decades! It was just hidden until Trump accelerated it!

Define Democracy? Start at the beginning with the words: "Constitutional Republic" This is going to be good folks!

do you need to earn more points before you can complain about the Eagles game or something...?

Not all republicans. 

And none of those republicans who are protesting the electoral college certification actually think they can overturn the election.  That's not what it's about.

Trump, on the other hand, is a criminal.   Honestly, about the only defense he has for that phone call to the Georgia Secretary of State is mental illness.   Everyone else on that call from Trump's team should be ashamed and probably in jail too.
