I predict there won’t be an election in 2048.
I’ll bet that in 2048 there hasn’t been an election for 20 years.
That will be the state of the US probably no later than 2020. We are becoming a one party state like Russia, Venezuela or anyplace else the the socialists have taken power and held it for a protracted period. The election of 2012 was the last chance to break the hold of the Democrat machine. By 2016 they will have had a decade to put their people in place in every part of the judiciary and bureaucracy. No matter which party wins the elections after that point, the socialists will be the ones calling the shots.
Even if a solid conservative wins the White House every effort he/she makes will be thwarted by bureaucrats and judges put in place by Obama. No president can survive that level of backstabbing and leaks, especially with a press that is all to eager to support the socialist party's line.
