A day after telling Iowans their beloved ethanol subsidies will have to go, Republican presidential candidate Tim Pawlenty used a stop in senior-heavy Florida to call for reining in Social Security and Medicare benefits for future retirees…

It's part of a tough-medicine tour, designed to highlight Pawlenty's willingness to tell "hard truths." He's also planning to visit Washington to call for less-generous pay and benefits for public sector employees and to New York to call for an end to Wall Street bailouts…

Pawlenty said Social Security's retirement age must "gradually" increase for people who are not yet in the system. He also called for ending cost-of-living increases for wealthy retirees. He said he'll release details soon and said the changes would not affect current retirees.
