Arguments from Global Warming Skeptics and what the science really says
I'd vote for anybody but a Republican. The Republican Party has fallen hook line and sinker for the Corporate subsidization of the hard line against the very idea of global warming. That means that Republicans stand aggressively against clean water, clean air, and renewable energy.
The science is complicated, but this much is very clear. If any of those Republicans running for office put their head in a paper bag and started breathing CO2, they'd pass out pretty quick and maybe even suffocate. I don't recommend that experiment to anyone. It's not that CO2 is a pollutant, it's that the percentage of CO2 and O2 is wrong.
Adding CO2 to the earth's atmosphere forces the earth's climate to change. Polluters, deniers, and, alas, Republicans are all for changing the earth's climate. I'd vote for anybody but a Republican for this reason alone.
