Although it appears that little will be accomplished at the Copenhagen climate summit fiasco, the chance that this or future negotiations could produce an international treaty again demonstrates the wisdom of the founding fathers. Given Obama's apparently limited concern about advancing U.S. interests, and the tendency of Democrats to swallow radical environmental doomsaying and support drastic, harmful "solutions," it's a good time to remember that treaties must be ratified by a two-thirds majority of the Senate. This is an excellent protection against the whims of presidents and parties in power. Getting 60 votes in the Senate to stop a filibuster is difficult enough. Obtaining a 67 vote majority is an order of magnitude greater.
Should the time come when the president commits the U.S. to a harmful climate treaty, one which would cripple the U.S. economy, waste taxpayer money in hand-outs to the third world, or impose other conditions damaging to U.S. interests, the Senate represents America's last line of defense. It's one of the many reasons to vote Republican in 2010.
