Interesting conjecture, considering John Edwards is perhaps dealing with a woman scorned! She calls John Edwards to the Hotel with a sob story, makes certain Edwards will not be Vice President, and receives a cash settlement from the National Inquirer! She is paid to get even.
Maybe she threatened suicide and he was terrified that the police would find a note pointing the finger at him so rushed over there.
That accounts for one visit but what about the second unless they were blackmail pay outs if he did truly end the affair in 2006.
