I've been telling my wife lately, "Remember, Bush got elected the second time."
There are many idiots in the US that want more government services and less taxes, while they max their credit cards and can't pay their bills, so the connection you would expect simply isn't there.
One thing I believe is happening. The politicians say the ridiculous things to pander and get reelected while maintaining more good policy than the Bush voters can follow.
For example, around the Chesapeake Bay, along the coast, local municipalities are starting some infrastructure for higher tides and seas and stronger storms while the Rush Limbaugh climate change deniers argue it isn't happening. That's not to say US policy has actually gotten excellent - we, like all governments, have a long way to go.
And if you dig through information contained in Obamacare, like research at Johns Hopkins and the Mayo Clinic concerning experiments in preventative health care, there are good things that smart, albeit quiet people, are doing in the US.
If things go south (no pun intended), is there room for another million immigrants in Great Britain? We are hard workers.
edit: There was a good NPR story yesterday about northern European (think Norway) high government service and the impact on average happiness.http://hereandnow.wbur.org/2014/01/02/big-government-radcliff
