You know, I've never seen a attack ad/article like what you came up with? It's weak.
Sorry for not actually creating a template, but it'd be more along the lines of attacking somebody for having a liberal arts degree - not a science or engineering degree to indicate that you've been trained in how to assess the dangers of mining/drilling in an area. Revealing that they're getting money, or at least have ties with, people that the target audience don't like and don't think should have a say in their business. Example would be Bloomberg's 'donations' to help spread gun control in the USA. It's often counterproductive because, well, the gunnies* hate him so bad. The Koch brothers would be the ones from the opposite side of the fence. They seem to like donating to 'any' conservative republican running against a liberal democrat in a competitive campaign. They don't really care where.
Depending on how bad they are, you could also accuse them of simply being NIMBY or BANANA - Not In My Back Yard, or Build Absolutely Nothing Anywhere Near Anybody. Fact is, we need resources to power our economy, and if you give the impression that you oppose EVERYTHING(and there are people who do), or your plan amounts to powering the economy on fairy farts, perhaps your efforts to constrict expansion should be restricted.
I say all of this as an anti-coal, pro-nuclear type. I think that the republicans have a point about the EPA - every regulation needs to be examined thoroughly, but consider diesel vehicles. Do you realize that because of the latest round of emission requirements, mileage in new diesels has dropped 20-30%**? We're talking about stuff like new hybrid buses getting worse gas mileage than their older non-hybrid cousins. The city can't afford to run the new buses in long routes because they don't save fuel. They WERE saving fuel until a new EPA approved engine was put in...
Anyways, to get back to the point - a single person 'rolling coal' with a deliberately modified truck in protest of the EPA's rules negates the benefits of the systems they mandated on about a thousand other trucks(and yes, those that do so are assholes). Personally, I think that the EPA needs to place stronger emphasis on retaining gas mileage, because we need to conserve oil. At this point the EPA is increasing fuel consumption and CO2 emissions for reducing other emissions - and I don't think that it's worth it.
*Given his staunch support for gun control and the fact that while Mayor of NYC he attempted to increase gun control on a GLOBAL scale, often donating money to gun control initiatives in individual states across the country I can see why.
**At least until you rip out the extra EPA stuff or reprogram the chip. Then you get the gas mileage back Details on modifications necessary depend on vehicle and emission system.
