The republicans are emphasizing that this is what the democrats may do, while claiming they (the Repugs) have done no such thing.
And what the Repugs have done might not meet the historical definition.
A more accurate terminology for what the Repugs have done could be "Hijack the Courts".
Democrats are now attempting to Free the Courts from this successful hijacking at the hands of procedural terrorists -- - McConnell and his cronies, and the dark forces behind them.
