It's actually the reverse.
Democrats don't just need enough votes to win.
Democrats need enough votes to overcome the massive organized Republican cheating campaign.
Republicans dialed the cheating up to "10" in 2020. It wasn't enough, so Republicans have announced they'll be dialing it up to "13" in 2024.
Look at the Republican fraudsters here, lying about the "2000 Mules" fraud just so they have an excuse to cheat harder. Like I said, they're all proud of how much cheating they're going to do, and they're not shy about announcing it.
