It's long overdue. It's time for a well known established businessperson who doesn't have the stain of a Romney and has the money to run and have 50 state ballot access, and 15% in the debates. It's long overdue.
So Ross Perot redux?
It seems like we're overdue for a strong independent/3rd party candidate. Every 8-12 years recently there is one who does pretty decently - 2000: Nader, 1992/1996: Perot, 1980: Anderson, 1968: Wallace
That's mostly historic accident.
1968: Racism
1980: Hatred of all candidates
1992/1996: Big money
2000: Clinton's neoliberalism driving progressives to the last straw
As regional polarization increases, so does paranoia about "spoilers." Thus, third parties have little to look forward to. The Libertarians did quite well in 2012, but nobody noticed because it was less than the Obama margin of victory.
