Paul's plan is weaker by far. His plan would cut a few taxes that constitute a small fraction of federal revenue, and doesn't mention eliminating the income tax (which would make his plan require either massive borrowing or touching the third rail of entitlements). Our Pure Principles Platform eliminates the entire income tax.
His plan would cut some military bases and freeze "discretionary" spending while giving entitlement spending a free pass. Our Pure Principles Platform calls for "the abolishment of all federal programs and services not required under the U.S. Constitution", and for getting the government out of the entitlement business (education, healthcare, retirement, and income security) altogether. His plan would make the Fed a little more transparent and legalize private gold or silver currency. Our Pure Principles Platform goes further, saying individuals may use any commodity they want as currency, and that there should be "unrestricted competition among banks and depository institutions of all types." His plan would "repeal" or "reform" (how can it do both?) Sarbanes/Oxley, and ease regulatory burdens on "community" financial institutions. Our Pure Principles Platform calls flatly for "the abolition of all regulation of financial and capital markets" (i.e. aside from force or fraud).
