This is disingenuous. It's one of many in that it may have contributed 0.0001%. If they wouldn't have done that, would they currently have more power? Absolutely not, believing otherwise means being clueless about what has motivated people to vote in certain ways.
It's definitely more than .0001%. Look at the campaigns. How much time did the GOP spend harping on windmills and solar subsidies and "clean coal". Calling out democrats for trying to make the environment better at extra cost to US citizens was a huge part of their campaign.
