Good or bad, no one is going to beat Trump except Biden. I'll take the last 4 years we've had, where he's had times that he seems out if it, but the country is doing a lot better and doesn't seem like we are at each other's throats. If he dies the day before election, I'll vote for his corpse.
If I'm not mistaken, Biden could add seats if he wanted to, so could any president. I think no one wants to do it because then the other party would add more as well.
I just played the music I've always wanted to listen to. If there was bad words, I'd either turn down the volume at that point or skip that song.
