2016

Why wouldn't they be?

In the past there have been longer periods of unbroken White House control by one party, and the underdog party remained intact.

Because of the fact that they have such high hopes and if they crashed that bad their would be such internal uprisings

You seem quite certain of this.  'Internal uprisings' I might agree with you on to an extent, but to suggest that the Democratic party itself would somehow collapse or whatever and be replaced by 2016 is a stretch.  The GOP survived the unexpected disappointment of the 1948 election, didn't it?

I think then though the party was united for the 48' election, the Democrats are already in shambles and with the media of today any internal uprising will get overplayed and could lead to the party splitting in two.

no it won't I see the Democrats going along with Northeastern liberals for 2008 and 2016 before finally turning towards a nomenation of a more moderate to conservative Southern or Midewestern Democrat. Maybe someone like Harold Ford, Mark Pryor, Claire McCaskill, Brian Schweitzer, or someone of those poltical leanings.

Oh, for f**k's sake, not another "the opposing party might die off" wet dream.  If the Republicans could survive through the days of FDR and Truman, the Democratic Party can survive another Republican presidency.  Need I remind you that the Democratic Party currently holds a majority in both sections of Congress, something that the Republicans did not even come close to doing during most of the days of FDR?  The Republicans were practically a nonentity during those days, and they came back.

The Democrats can survuve another 8 years of a Republican Presidency, They are most likely going to be holding both Houses of Congress for a while too.
