I think you're wrong when you doubt whether Reagan could win today. Similarly, Ron Paul could and would have won. Obama is a disaster... BUT
Domestic policy is not the only consideration.
This from a Ron Paul- supporting libertarian website:
"To me Mr. Romney’s candidacy signaled the Republicans’ admirable capacity to do the impossible: find an aspirant even more depressing than Obama. But they managed. It was a triumph of the human spirit. Never underestimate American ingenuity.
How was this result achieved? Mr. Romney asserted that Russia is America’s most perilous adversary, wanted to deal fiercely with China, asserted the nonexistence of Palestinians, pledged his undying troth to Israel (America presumably would be a second wife), wanted to attack Iran, and thinks we need to increase the military budget.
Oh god. Oh god."
WWIII right now? That's a big deal.
And "Conspiracy Theories"? Sure, they're true. You'll see.
