Marco Rubio is a conservative senator with a record of opposing corporate welfare in all corners of the economy, except one. That would be in the swampy fields of South Florida, where they grow sugar cane.

Rubio supports the federal sugar program, with its special cheap loans and its blatant protectionism. This is to the detriment of U.S. consumers and foodmakers, and to the benefit of a handful of sugar magnates, including some of his earliest fundraisers.
