The voting populace who are now largely investors, speculators gamblers (stocks, bonds, housing, small biz startups, you name it) turned into big Govt, bail-out Democrats in 2008 when they thought they could lose it all. Like vacationers on a cruise ship rushing to the other side because the loud speaker announced “ice cream on the lido deck”, voters in 2010 have shifted back to the right because they now “fear” they won’t get more than their fair share. Greed and fear, as usual.
Or as Roubini puts it, big biz privatizes the gains and socializes the losses!
