Logic vs. Lunacy

This campaign presents two choices...a choice between real ideas to solve real problems:

What do you see as the gravest long-term threat to the U.S. economy?

Obama: If we don’t get a handle on our energy policy, it is possible that the kinds of trends we’ve seen over the last year will just continue. Demand is clearly outstripping supply. It’s not a problem we can drill our way out of. It can be a drag on our economy for a very long time unless we take steps to innovate and invest in the research and development that’s required to find alternative fuels. I think it’s very important for the federal government to have a role in that process.

and lunacy:

McCain: Well, I would think that the absolute gravest threat is the struggle that we’re in against Islamic extremism, which can affect, if they prevail, our very existence. Another successful attack on the United States of America could have devastating consequences. You’ve been a supporter of climate-change legislation that would essentially impose a penalty on the use of fossil fuel.

Bereft of useful ideas to solve real problems, John McCain and the GOP will play the fear card. The basic campaign theme literaly appears to be "elect John McCain, or we are all going to die!"

How can a major political party continue to be viable with a fringe idealogy?
