No. I could care less if Reagan gets credit. Its more the fact that it was the Fed policy not tax policy that spurred growth. I don't want that myth perpetuated. Its not based in fact, its was a coincidence.
Volcker fought inflation during Carter and early Reagan (remember Reagan wasn't looking good in early 83) by jacking up interest rates to fight the inflation which caused a recession, then when he lowered the rates the economy came back. It happened to coincide with the tax cuts.
Also, he hired a lot of government employees (mostly in defense, but still, shiftless government workers!) and oil prices dropped at an opportune time as well. As with most successful President's, Reagan was lucky.
Oh, and last night's Real Time was pretty horrible. In the Israel segment, you had Jane Harman, who almost lost a Democratic primary due to her hawkishness, a Washington Examiner guy, and Maher all circle jerking about how Israel were the real victims while Nate Silver just sat there.
