By September 2009, McCain had largely disengaged from the climate change debate, and criticized the Waxman-Markey Climate Change Bill out of the House as "appear[ing] to be a cap & tax bill that I won't support" and having "a lot of special deals for a lot of special interests." The senator also had both substantive and procedural objections to the cap-and-trade bill being worked on in the Senate. In February 2007, McCain and Gov. Arnold Schwarzenegger called for a nationwide roll-out of California's new low carbon fuel standard. In April 2007, McCain proposed moving from exploration to production of plug-in electric vehicles. In late June 2008, McCain said he favored nationwide limits on carbon emissions from cars, saying "my goal would be to see a federal standard that every state could embrace". In mid-July, McCain, regarding whether states such as California should be permitted to set tough greenhouse gas limits on vehicles, that "It's hard for me to tell states that they can't impose ... whatever standards that would apply within their own states." He said "I guess at the end of the day, I support the states being able to do that." In 2007, McCain sided with Bush against Florida Republicans in opposing a Congressional override of Bush's veto of a water projects bill that would have approved $2 billion for restoration of the Everglades, despite $7.8 billion that had been earmarked for the Comprehensive Everglades Restoration Plan (CERP) in 2000. The State of Florida has, since the passing of CERP, spent $2 billion on CERP initiatives, though the federal government has declined to fund initiatives written in CERP. In 2004, a group of real estate developers, led by a major fundraiser to McCain's campaign, Al Hoffman, worked to block state efforts to follow through on restoration works. McCain said on June 4, 2008 while touring the Everglades, that he supported "adequate funding" for restoration but that it had to be achieved "without sacrificing fiscal responsibility", though he declined to state which CERP programs were irresponsible. The Colorado River Compact allocates the water of the Colorado River among seven states. McCain called for renegotiating the Compact, a statement that has been interpreted as a suggestion that less water be reserved for the Upper Basin states (Colorado, Utah, New Mexico, and Wyoming) in order to provide more for the Lower Basin states (California, Arizona, and Nevada). McCain's 2006 rating by the Almanac of American Politics (2008) on Social Policy was 46% conservative, 53% liberal. (2005: 64% conservative, 23% liberal.)
