Twitter already let him back on. He’s sticking with Truth Social. Good for him. I’m back on Twitter now, but not very active. Never was.
Truth Social is where he preaches to the MAGA choir, to 1/10th the number of people who follow him on Twitter.
If he wants to be a serious candidate, he's going to have to resume posting on the mainstream (aka popular) social media sites. He's going to need more than the MAGA faithful to pull him across the finish line.
He might also want to hire a social media team to, at the very least, proofread his posts.
