I didn't know that this had happened. Apparently, they've refused to certify hundreds of elections, just in the last four years.
In Georgia, three election-denying (on the record) MAGAs have joined the state election board. The board is on the verge of passing a rule that says that election certification must be unanimous--therefore, one single MAGA can stop Georgia's votes from being counted indefinitely.
The law is unclear re what happens when a state is unable to report its certified election results. It's clear, given the states where the MAGA election deniers have been placed, that the Republican strategy is, should they not be winning the election legitimately, to throw the Electoral College into such chaos as to force the election's outcome to be decided by the House or the Supreme Court--both are venues where they would win. This chaos could also exist at the local level, when a precinct/town/county refuses to report its results to the state, thereby delaying the state's results indefinitely.
These Republifucks reallty do hate democracy, and this evil scheme to subvert it has pretty much flown under the radar.
