I really don't think Biden will win. He is a terrible candidate, and when I travel along the comments sections of various articles, even the die-hard democrats limit themselves to saying "Vote Blue!" Rather than "Vote Biden!", or any such language that would denote enthusiasm or belief in him personally. They just want to see Trump lose. They know Biden would be a sh*tty president, even if he had all of his mental faculties. They are pretending for the sake of political expedience, nothing more.
And the blue-dog voters are none too enamored of Kamelface Harris, either. She was yet another lost gamble by the DNC. They thought her almost-blackness would spark enthusiasm in the minority and self-hating white contingents, while being non-threatening enough to keep the semi-secretly racist WASP-types who fund everything comfortable. I estimate the success rate of this specific strategy to be about 20% of what they thought it would be.
Unfortunately, she is arrogant, snarky, and not-as-smart-as-she-thinks-she is. She hasn't won anyone over, least of all the well-educated black women voters. They've seen her type before, and whether it's on campus or in the work-place, she's the chick who is an obstacle to getting your job done, getting that raise, perk or promotion, because not only did she sleep with the boss, she will make you miserable because you didn't. With a fake smile plastered on her face.
The Trump Train, however, seems to be full steam ahead. Even in South Florida, a notoriously deep blue stain on the otherwise red state of Florida, there is a noticeably higher ratio of Trump gear in evidence, if you go by lawn signs, bumper stickers, etc. I would estimate it as at least 5:1, and I am being conservative. There have been a lot of boat parades, from Jacksonville in the north all the way down to Key West, with people decorating their vessels in banners and American flags and whatnot. That's kind of awesome. And every time he shows up in Miami or West Palm Beach (to go to Mar-a-Lago) there are thousands of fans at the airports, on the streets, at the rallies. He's got full-on rock-star status.
I predict a solid win by Trump, both in popular (comfortable lead) and electoral (landslide) votes. The dems in Congress will protest and try to drag things out, but, like every other tantrum, they won't accomplish anything but further irritating the taxpaying public. Three weeks sounds right on the money. They'll use up most of the active time left in session, and get bored with it just in time for their winter break. They usually take the last 3-4 days to sneak through some funky bills while everyone is busy with holiday preparations, but I think Trump will stymie that, and maybe hijack the strategy and force through a bill or two of his own.
I also predict that the repubs will pick up a few seats in the House, owing to the fabulous spate of new candidates vying for seats, including Carla Spalding, Joe Collins, Kim Klacik and Carlos Gimenez. Idk if it will be enough to sway the overall balance, but it will definitely keep things interesting.
