Is Hillary losing her grip on reality, or is she the 3rd Party candidate? Surely we saw when Joe Lieberman run in 2006 after he lost the primary he felt was denied him and decide to run as an independent, but that was for a senate seat.
Ross Perot formed a third party, but he did not run in any primaries, save his own.
Then there were the Dixiecrats who ran Strom Thurmond in 1948, after a credentials fight. But what strikes me as interesting is that in 1912, Teddy Roosevelt did not accept the fact that the Republican party chose to renominate the incumbent, William Howard Taft. So Roosevelt continued on after losing that bout and created his own party, The Progressive Party, sometimes called the Bull Moose party.
This split the Republican vote and Woodrow Wilson headed to the White House.
With all the votes seeming to be in Obama's favor, nomination-wise that is, what is Hillary playing at? She claims she's ready to lead on "day one," or so she says, but real leadership is knowing when a cause is lost and when it's time to quit.
And on this one, she is like George W. Bush. The surge is on and victory is around the corner and don't tell either of them anything else.
In the end, if her intractability prevails, she may end up in history books as the spoiler of 2008.
