Dems actually have lots of younger leadership; names like Elizabeth Warren, Tim Walz, Sherrod Brown, Gretchen Whitmer, Beto O'Rourke, and Gavin Newsom come to mind off the top of my head.

You have a slowly dying Trump, and young 'leaders' like Rubio (maybe your best hope), Hawley, Tuberville (ok, he's not young), Haley, Vance, Noem, and other similarly awful, mostly Trump-linked candidates. I'd run Rubio and Haley, FWIW.

A drift back toward rationality and bipartisanship wouldn't hurt. Bring Mitt back into the Party.
