Biden didn’t say that Palin and Trump were equally ignorant. He didn’t say they both lie. He didn’t say they are both losers. He did say he’d rather debate Pailn than Trump.
Biden describes Trump’s behavior as “outrageous,” astounding”, and the “text book definition of sexual assault”. It is totally believable that Trump took women to dinner in his limo, that he described his sexual encounters with other women and rated them, then made the women walk on a table to exit the booth in which they were seated. The purpose of making the women walk on the table was to look up their skirts and describe their undergarments or genitals. While some have denied this claim, it seems totally consistent with previous stories about Trump. Further, the accuser was very specific in details of who was at the dinner and recounted a story that was new and different than previous allegations of sexual harassment. If a woman was going to make up such an allegation, it seems likely that she would simply allege that Trump had done something to her that he’d done to other women. That would be totally believable. Instead this report is outrageous enough that it is too strange to be fabricated. It’s like asserting that Todd Palin’s private part is bi-colored. It is unusual enough that it seems the person making the report would have asserted something much more ordinary if they were making up a story.
