I like the cleaner logos. This is a logo that will end up on merchandise like T-Shirts, mugs, bumper stickers. It also will be used to try and create federal legislation, so it has to be VERY professional. It needs to be something quickly recognized and very professional.
So far, I'm not blown away by a logo that really tells me what we're trying to do, which is raise the tax on oil. I do, however, like the clearner logos. I think they're getting close.
Importantly, this isn't going to discriminate against foriegh oil over domestic oil. The idea is to raise the tax on all oil, to srive the ultimate cost of oil related product (like gasoline) up.
