They might have been able to resist once they got through the primaries, but the retirement of Kennedy will raise the stakes. They backed themselves into a corner with the various filibuster policies, and they are going to have to pay the price for that.
Socialist calls for burning down the opposition's tent
This sort of hateful advocacy of violence is (and probably should remain) legal, but should also be heavily criticized and denied an audience by responsible organizations. Those who call for violence against their political opponents should be lonely, solitary voices lacking in support, platform, or audience.
Unfortunately, we're seeing increasing calls for violence from people with support and with audiences, including this young socialist idiot.
Some would stop and ask whether the typical response to calls to confiscate firearms ("Molon Labe!", meaning, "Come and take them!", a reference to the last stand of the Spartans at Thermopylae) is a call for violence. It is, but it is a call for violence in defense of self and fundamental rights, and it occurs in the context of defending the principles of the nation's founding. Governments which attempt to confiscate guns violate the 2nd Amendment and the contract that grants them their powers.
The difference between violence in righteous self defense and just burning down the tent of the political opposition because you hate them and want to smash them is vast.
