There's exactly as much evidence of that as there is of Ms. Ford's rather ridiculous story that he attempted to rape her at some unspecified date, time, and location 35ish years ago.
Not really. Ford overplayed Feinstein's hand. Before she came forward, the Democrats could keep teasing the 'anonymous' letter and release more details as it became convenient to put pressure on Grassley/McConnell to delay the vote - while also giving political cover for the Democrat Senators at risk of being ousted in November to not vote for Kavanaugh. The dingbat coming forward gave the GOP someone to investigate, someone whose credibility could be challenged, and gave Grassley someone to invite to be heard and questioned by the committee. When Ford refuses to appear on Monday, her story is dead in the water.
