The LA Times has endorsed John McCain in the GOP primary, and at least two of its reasons for doing so should give conservatives pause: the liberal paper likes McCain because he's weak on border fences and strong on global warming.
Excerpts [emphasis added]:
As the Republican field indulged this campaign season in an orgy of ignorance on immigration, McCain stood his ground, sponsoring legislation that would provide a route to citizenship for the 11 million to 12 million immigrants here illegally. His rivals have argued for mass deportations and strong border fences.
Similarly, McCain has led his party in its halting effort to confront the reality of climate change. He introduced the Senate's first attempt to address the problem legislatively in 2003, and although that bill failed, McCain has supported cap-and-trade systems that could reduce greenhouse gases, and he has stayed that course despite criticism from fellow Republicans.
