While he is willing to consider a mail-in vote, Crist argued that "the Democratic National Committee should come to the common sense conclusion that the right thing to do is to honor that vote, recognize that vote, and seat those delegates."
But even with three large states potentially yet to weigh in — Florida, Michigan and Pennsylvania, which holds its primary on April 22 — it's possible neither Obama nor Clinton will have enough delegates to claim victory at the Democratic National Convention in August.
The last brokered convention to produce a winning candidate was in 1932, when Democratic bosses, led by Joseph P. Kennedy, left the floor and chose Franklin Roosevelt in a smoke-filled room.
This time, a brokered nomination would be different: The party bosses are now elected officials and the rooms are smoke-free.
But the pressure — that hasn't changed at all.
Dean's fears of a brokered convention may be justified. In the two brokered conventions since Roosevelt, the badly bruised nominee lost the election.
Since Roosevelt, nominees bruised in brokered convention battles in which there was more than one ballot — Republican Thomas Dewey, who was pronounced a presidential winner only in a famous Chicago Daily Tribune headline mistake in 1948, and Democrat Adlai Stevenson four years later — have lost the general election.
