You are incorrect, Republican Deficits go back to Nixon, but RayGun and Dubbya's Dad went even farther into debt before Dubbya. Right Wing Nuts cut back on taxes, but never cut spending by a comparable amount. As for Obama, the house and the Senate were controlled by Republicans, so there is blame on both sides of the political fence. Budget Brinkmanship. Clinton and Carter made some progress at debt reduction.

RayGun fans like to claim that by the time he left office, and admitted that he was senile, USA Federal Tax Revenue had recovered to the same numeric $ value as when his handlers started slashing taxes for their rich buddies. Those same RayGun fans change the subject when I point out that a USA $ lost half its value on RayGun's watch, as a result of high interest rate policies.

He may be Reagan to some, but to me SDI aka Star Wars makes him forever RayGun. All those billions wasted and they still can't intercept a missile, even when they know the launch time and trajectory.
