Democrats (read Communists) ALWAYS toe the party line! It's Republicans that can't seem to get their act together.
Democrats accept the possible .... it keeps their momentum moving. They know, with certainty, it may take more time, but they will achieve their goals if they move but an inch AND continue to slow their opposition.
Republicans embrace the perfect ... slamming their momentum into a brick wall, stopping it cold and breaking it apart. They are prepared to take their marbles home, content in their certainty that the glorious, perfect moment will come and they will rise from the ashes.
