Democrats want America to be energy independent. As long as it doesn't involve the pipeline. Or fracking. Or any new dam, coal plant, nuclear plant or oil refinery. But wind is good, as long as it isn't near any beach used by a Kennedy. And solar is good, even if it does set birds on fire.
Transporting oil across the country is also fine with Democrats, as long as it's done on Warren Buffet's trains. That is worse for the environment than a pipeline, and that's what would continue to happen if the pipeline is not built.
Let's put it to a test this winter. Create a national regulatory system that requires Democrats to heat their homes with wind, solar and burning corn cobs this winter, period. What is good for the goose, is good for the goose.
