@15 - Well, forsooth on how people vote.
But its a bit of a shock to see a history of the collapse of the New Deal coalition that does not include a mention of the mid-century civil rights movement.
FDR did nothing about segregation because that was the price southern democrats demanded for their support of the New Deal. Truman didn't continue this arrangement, integrated the military and Strom Thurmond et.al
. bolted the party in response. That's where the Dixiecrats came from - in 1948. FDR had been dead for 3 years by then.
Eventually, all those ye olde segregationists migrated to the GOP where they (or their ghosts, at least) remain to this day.
This, combined with sustained, systematic attacks on industrial labor unions (the most devastating of which has been the movement of production out of the country to jurisdictions where they're only too happy to shoot stikers dead in the street), is what broke the New Deal coalition.
There will be no recovering FDR's coalition, no matter how polite the city mice are to the country mice. Because the world that gave rise to that coalition is long gone. Farmers are just another type of industrial capitalist now.
