“Gallup: Americans’ Global Warming Concerns Continue to Drop“. Anthony says that a Gallup News poll shows that the denialists are “winning”.
Exaggerated? Only when the Republicans are shouting the loudest.
But Anthony conceals the fact that all the “gains” have been within Republican voters. Read Gallup News’s follow-up analysis, “Conservatives’ Doubts About Global Warming Grow“.
Who's getting their science from Sarah Palin?
Climate Progress discusses this in this post: The disinformers are winning, but mostly with the GOP – New Gallup poll shows sharp partisan divide in understanding of climate change.
Wott's Up With That? 
Although a bit older, in their 2008 national survey titled A Deeper Partisan Divide Over Global Warming, The Pew Center for the People & the Press show that only 27% of Republicans believe that global warming is being caused by humans compared to 58% of Democrats. Even more disturbing, only 19% of Republican college graduates say that there is solid evidence that the earth is warming and it is caused by human activity compared to 88% of Democrats who are college graduates.
