It is quite possible that the seating of FL and MI delegates on the credentials committee will make the difference between them ruling to seat the delegates or not.  Now, imagine that Michigan selects largely Clinton supporters for the 55 uncommitted delegates - the party leadership is very pro-Clinton.  Do the math with FL and almost all the michigan delegates going to Clinton and suddenly the pledged delegate race is essentially tied.

Will it happen that way?  Who knows.  But this move by the DNC makes it a real possibility, not a tinfoil hat scenario.
