The Kyoto Protocol and EPA regulations aren't optimal in combating the emission of greenhouse gases; there is a deep consensus among economists that a carbon tax is the best way of dealing with the issue. Can't speak for Kasich on this issue, but the day the US gets a carbon tax is the day pigs fly. That's a failing of America at large, not Kasich specifically.
Fuck, at least he acknowledges that climate change is real and something ought to be done.
This is meaningless.
Not really; Clinton also supports capital punishment. Having a Republican who is stringent with the practice is better than one who isn't.
