The Edwards endorsement does seem like the beginning of the end for Hillary. Here’s how it will probably play out:

Obama will get the nomination by the end of this month, but Hillary will not give up in anyway. It will become apparent that she is in fact a Terminator sent from the future. She will brutally kill John Edwards and Ted Kennedy with an electromagnetic health care policy pulse wave, which sucks the air and blood out of its victims causing a slow and cinematic asphyxiation.

Suddenly, as she’s about to terminate the one candidate who would have eventually saved the future by restoring hope, Arnold Schwarzenegger crashes through a wall. It turns out that he really is a terminator from the future sent back not to save Kalyfornia, but to stop HT 4 (Hillary Terminator) from destroying the future of hope.

In the ensuing fight, they crash through walls, overturn trucks on highways and destroy highway ramps and airplanes. Just as it looks like HT 4 is about to terminate the Gubernator by retroactively revoking his citizenship (through a wireless interface with Teledyne Cybernetic Systems), Barack Obama appears and saves him by hacking into the democratic donor database and terminating her funding. She immediately shuts down and Judgment Day is forestalled, but not permanently prevented. We know she will be back.
