And a unified pro-coal message from the national democratic party could help get KY and IN into battleground territory, get NC into Lean/Likely D territory, keep OH/PA from continuing in any republican trend they may or may not have, and maybe make up some ground in parts of Tennessee and Oklahoma. So Democrats would really benefit from being pro-coal. Dem voters who are against coal would just hold their nose and vote for the party anyways. I mean, who else are they going to vote for? The Greens? ROFL
"Let's sacrifice the environment to secure our political future 'cause what else are those pro-renewable voters going to do? Vote for the Greens? ROFL"
