The consequences was losing the election in 2020, no? I mean Democrats are really, really, really bad at fighting back. Like bringing pool noodles to a gun fight bad. But saying they do nothing is a bit much.
It's not really a consequence, more like a slight slow down of their plans. All Democrats really do is not make things worse cause as soon as they "try" to make things better they run into some problems that you know the Republicans would never let stop them. So that just means losing elections is just a slow down rather than a serious consequence for Republicans cause eventually people will get tired of the Democrats not being able to do anything and end up either not voting or voting Republican.
