Presidential election

Courtney • fiancé 💍 Boy Mom 8/2020💙 Expecting #2

So I’m on twitter and I came across this and I’m just really shocked at the amount of people registered to run. As a person commented, is this usual?? Are they just choosing anybody now? I know they’re gunna have to make cuts as there can’t be 500+ candidates the cictizens will choose from. What are y’all thoughts on this?
