Oh bother. Cribbing research from a blog, especially when it comes with the disclaimer that "Site content may be used for any purpose without explicit permission unless otherwise specified," may be lazy, but it isn't really plagiarism. It's not even the same thing that Biden did.
Even then, politics is different than journalism. Does anyone think Bush writes his own speeches? No. But do we consider what he says in his own speeches his words? Yes. Does he give credit in the speech to his speechwriters? No. Is that plagiarism? No.
Domenech wasn't a politician delivering a message -- he's a journalist producing content. Big, big difference.
I honestly don't know that there is such a thing. Gasoline is not, in and of itself, healthy or unhealthy. It's the way an automobile processes it that impacts on the environment. So, first and foremost, if you want to reduce the impact of the gas you do use, drive the most fuel efficient vehicle you can afford. Even doing little things like making sure your tires are properly inflated can improve fuel efficiency.
Alternately, if you can, look into diesel vehicles. Diesel is a dirtier technology, but for surprisingly not much money, you can have a diesel vehicle converted to run on bio-diesel, which is not a fossil fuel.
My larger point in all of this is that we shouldn't fall for corporate greenwashing campaigns like BP's. In other words, just don't go out of your way to reward BP for an ad campaign.
Perhaps a better question would be if people would be more enthusiastic about supporting Hillary Clinton for President if she picked Feingold as a running mate. I'd be quite interested in seeing those numbers from the netroots.
