Gov. Susana Martinez, who has touted herself as a champion of transparency, on Friday vetoed a piece of legislation that would have required greater public disclosure by those who spend big money in New Mexico political races. The governor vetoed Senate Bill 96, a goal long sought by good-government groups and those who wanted greater information on the influence of money in politics. “While I support efforts to make political process more transparent, the broad language in the bill could lead to unintended consequences that would force groups like charities to disclose the names and addresses of their contributors in certain circumstances,” Martinez wrote in her veto message. One of the legislation’s sponsors, Democratic Senate Majority Leader Peter Wirth, responded to news of the veto Friday morning. “I am disappointed but not surprised that the Governor would side with the Koch brothers and ALEC (American Legislative Exchange Council) and ignore the 90% of Republicans and Democrats in New Mexico who support campaign finance transparency.
