Dave's premise - that high gas prices hurt the economy - is certainly valid, even if his numbers are skewed. I'm not sure there's much remaining to be said about it though. The President doesn't directly control gas prices, and while I'm all for opening areas like ANWR (at least within certain constraints), I doubt that any new President can do a lot to lower gas prices. Once oil suppliers learned that the world will buy oil at $80 to $100 with modest drops in demand, I doubt anyone can drop oil down to $15 to $30 again. Not until there's a fundamental breakthrough and/or transformation in energy production and use anyway. So while I don't think it's a troll thread, one could argue it's outlived its usefulness.
Personally I prefer threads to continue until they get offensive (mods' call) or people naturally stop posting, but I'll admit I have no strong feelings either way.
You have to look at who the person keeping the thread alive is. His sole purpose on this forum is to troll.
Just look at his earthquake prediction threads, his other $10/gallon gas threads, his milk threads...he goes as long as he can get away with it.
Even if we try and let it die, he posts some article about how gas is above the national average next to a airport rental car return. Or he will use premium gas to skew the facts.
It is the very definition of trolling.
