As a small-l libertarian, or as I like to call it, a "minarchist," I'll answer anyhow, and skew your quiz regardless.

1. Von Mises and Hayek, very much so. Also Karl Popper.
2. The Coolidge Administration.
3. Not particularly, although I'd be interested to see if there's any good economics indicating that the increased liquidity from increased small deposits produces a common good worth the distortion of the market.
4. 7.5, based almost entirely on his foreign policy of kicking the hell out of fascists.
