I wonder if any young celeb will shoot themselves in the foot and reveal that they're supporting him before election day. The closest I can think of so far is Trisha Paytas who lost a lot of subscribers. Clint Eastwood even got backlash being an older male. It would be career suicide unless they're willing to milk it and become a laughing stock like Stacey Dash.
What? Gaga is famous in part because Trump put her on Miss Universe. That was the first time millions were exposed to her and her song "Just Dance". Only liberal media and hyper sensitive SJWs would care.
