Wow so it took only 4 weeks to go from TFG accepting fake endorsements from Swift, to Swift actually endorsing Harris, to Trump rage-posting about her.
There's a clip of Kurt Cobain at a Nirvana concert telling anyone in the audience who is a sexist, homophobic, racist, etc. To get the fuck out and to stop buying their albums and calling themselves Nirvana fans.
I wish more artists did shit like this, even if it cost them money.
This tells me that his team showed him some metric or statistic, showing that Taylor Swift's endorsement made an impact and is hurting him. That's why he's lashing out without even saying anything but I HATE HER.
Maybe he learned that all his young Maga meathead voters are switching to Harris, cause their Swifty girlfriends are putting the pressure on them!
