I have a hard time believing Hillary doesn't realize it's over. So, I'm left thinking that she is really continuing to attack Obama because she is hoping that he loses (and then she can claim she was right), setting herself up for a run in 2012.
Some people will argue that she has to stay in until the end out of respect for her supporters or until the race is technically over. I would have no problem with that if she focused on attacking McCain.
totally agree. Although after the Indiana/NC debacle, her tone changed a bit. However, I think she's trying to sabotage Obama so she can run again in 4 years - and hang on for a seemingly miracle shot at getting the nomination.... The problem is, Obama is really getting back on stride with his words - when he does that, he's above all the 'silly time' attacks, and that's key for him.
Also, I HAVE heard her allign herself with McCain on some things, undercutting the party.
