GOP presidential contender John McCain yesterday called for cutting federal subsidies for oil, gas, ethanol, and sugar and using the money to fund a school voucher program. A major theme of McCain’s campaign has been fighting special interests, and in going after the oil and gas subsidies, he strikes against an industry that is a major contributor to the campaign of Texas Gov. George W. Bush (R), the leading Republican presidential candidate. Last year, McCain introduced a bill that would have financed a voucher program solely by eliminating the ethanol tax; the bill was defeated in the Senate.
