I think your question supposes that most of them are aware of Peak Oil (probably true as of this year) and believe it is real.
Even if they believe it is real, their responses to that are as varied as we see anywhere else.
1. Thanks to [insert one of: Engineers, The Market, God], a miracle will occur just in the nick of time.
2. Thanks to [insert one of: Solar Power, The Market, Conservation], we will gradually and painlessly transition to the New Order.
3. I'm old, glad I don't have to worry about it.
4. I'm rich, glad I don't have to worry about it.
5. I'm worried, and I'm talking about it, but everyone looks at me like I was from Mars.
6. It's an election year, I'll worry about it later.
7. It's just to painful to think about, so I don't.
etc etc etc.
There's too much disagreement generally over how to respond to this, and in what time-frame, so why should we expect "the politicians", as a group, to agree on a response?
Personally, to the extent that people
can respond to it meaningfully, I think current fuels prices are an "encouraging" thing.
