I'm aware that people can get let down when elections don't go there way, but these hysterics are plain silly. Like when some conservatives worried that Obama might seek a third term. Plain silly.
Considering that where and when they could, Republicans gerrymandered the voting districts to give themselves the edge, and they still almost lose and during the Obama years, the Republicans did their best to inconvenience people who normally vote Democrat (like college students who are now forced to go home to vote), I'm with Bilby. Look at Guiliani. A great hero of 9/11. But he'd just lost the mayoral election. He decided that since the disaster was unprecedented, he should stay in office past his time...you know, to make sure things were OK. New Yorkers had to hound him out of office. And isn't NYC mostly blue?
Imagine great swathes of the nation being red or dominated by red thinking folks.
If a Democrat in the next presidential race looks good, all that needs to happen is some real or imagined emergency come up and those in power might think it's a good idea to postpone elections. Who could stop them? The Republican dominated Congress? The Republican White House? The Republican dominated SCOTUS?
It wouldn't take much.
