Even if the sexual assault allegations by former Joe Biden staff member Tara Reade turn out to be false there are still problems the former vice president faces. The first and most important of these is whether he can win his party's nomination. I'm generally suspicious when it comes to politics. Why has Reade waited until now to come forward? Biden has run for president before and several times for senator. He was vetted before Barack Obama picked him as his running mate. The timing seems too convenient.
