Had to look that one up. Rubicon. Kind of a funny term to use, but whatever. Hillary did win the popular vote, but that is irrelevant at this point.
I prefer to look at the next 4 years.
The Repugnant ones look poised to win the Senate, and probably keep the House as well. Putting Trump back in office as well is a frightening concept to me. 4 years of revenge, retribution, mindless and endless legal wild goose chases. Gutting just about everything. More tax cuts for millionaires. Gutting of the EPA, Dept of Education, etc. Wiping out any administrative officials that even smell like Democrats. Coddling of dictators Putin, Jung and the Chinese guy. Complete destruction of relationships with our European allies. Likely fall of Ukraine. Stacking the Administration with unqualified cronies. Further deterioration of Women's rights. Probably the one thing that wouldn't bother me too much would be a draconian crackdown on and shutdown of the border. And just a lot of hate and continued vitriol for the next 4 years. I would bet that there are a lot of Repugnant ones on Capitol Hill that would breathe a sigh of relief if he loses.
If Biden wins? With Trump out of the way (we can only hope), a possibility to bring back some civility and possible bipartisanship to address the many issues of the US. Starting with further Border fixes. Of which the bipartisan bill that was deep-sixed due to Trump's influence would have been a good start. That legislation WAS supported by the Border Patrol Union. An even-handed foreign policy. Is Biden kind of losing it? Yeah, but he's not THAT bad mentally. And younger than 14 members of Congress. Soon to be 12 when Feinstein and Napolitano retire in the fall. Now there is a whole 'nother discussion.

So to me it is a stark difference. And an obvious choice. You cannot tell me that Marjorie Taylor-Greene, Lauren Boebert, Josh Hawley, Paul Gosar, Kari Lake and their ilk are good for this country. And yes I can say the same for the Squad on the other side.
