What is Christine Braley Ford trying to hide?:

Most tellingly, before she came out as the accuser, she spent what must have been days scrubbing her social media accounts of all the lefty activities and statements she must have been involved in. That's the detail that stands out to me.
Why did she do that?
Just because someone is a lefty does not mean he can't be a victim of a high school groper.  Left-wingers would be the very first to point this out. Why did she scrub it?
Obviously, because it was to conceal her political agenda and make her case stronger as that of a random objective woman telling the truth, not a lefty activist desperate to make a difference for the Democrats.
