What might be a catchy hit to inspire the hearts and reinforce the identity of its majority following?
Stop being cucked pc libs, to borrow a phrase. Stop the institutional bullshit, no more civility nonsense, call trump a piece of shit and double down on it. When it comes time to talk policy, as in when you are specifically asked about it and not a minute sooner, talk about the opposition’s first so everyone knows it’s awful. Be aggressive, stop apologizing or trying to take the high road. Be a real god damned person! No fake bullshit, say what you believe and believe what you say. No more shrinking back for some non-existent moderate Republican, fucking stick by what you say and then go farther. Or if you genuinely do have a heelturn, be open about it and go harder in that direction.
Better policy would be very nice, but before any of that they just need to act like real fucking people.
