SEAN HACKBARTH: The Spirit of Fred Thompson Lives On in John McCain: “Last fall, Fred Thompson issued a tax plan that included an optional flat tax with two tax rates and a generous standard deduction. Another element of the Thompson plan was reducing corporate tax rates. I don’t know if Thompson and McCain have spent any time together since McCain became the GOP nominee. Like I wrote above McCain for some time has been talking about cutting the corporate tax rate. The optional alternative tax came out of the blue. I wonder how much influence Thompson had?”
