Politico's Jonathan Martin reports:
After hitting it in most every appearance he made in New Hampshire and Michigan, John McCain now rarely brings up the topic of global warming.
McCain's strong views on addressing climate change play well among independents and Democrats, but most of the GOP base either disagrees with him about the issue or just has little interest in it.
He didn't raise it often in South Carolina and, at a town hall meeting in West Palm Beach today, chose instead to focus his remarks on the economy and national security.
Senator McCain's not likely to bring up the Gang of 14 either. Or his votes against the Bush tax cuts. Or McCain-Feingold, McCain-Lieberman, or McCain-Kennedy.
Senator McCain has to spend more time remembering which lines not to deliver rather than the ones he must get out.
