Why is it when Biden forgets something, he's senile, but when Trump says something non-sensible, mistakes something, it's just normal Trump?

Trump forgets what country a world leader is from, what state he's in, confuses Nikki Hayley with Nancy Pelosi, forget he's not running against Obama, says stuff about airports in the American Revolution, and MAGA cheers, but when Biden forgets something or mistakes someone for someone else, MAGA cries "Biden's senile!"

Hypocrisy, plain and simple
Trump's not senile. He screws his words up and pretends to forget stuff up on purpose to rile up the libs

Imagine if Joe Biden had mixed up Nancy Pelosi and Nikki Hayley?
And Trump once called Tim Cook of Apple "Tim Apple"
The man literally taked about revolutionary war forces taking airports!
He was in ARIZONA the other day and said "Pennsylvania, remember this when you have to go to vote." You MAGA types know full well if Biden had done that, you'd say "See, he doesn't even know what state he's in!"
