That's the big question heading into 2011 and beyond.
If invasive silver and bighead carp do not take over and decimate the Great Lakes and its billion-dollar sport fishery, it probably won't be because the federal government stopped them. It likely will be because the exotic fish did not find the Great Lakes to their liking.
Oh, the feds have a plan and the President has appointed a carp czar, but Obama and his Illinois friends oppose the one effective means of keeping out the carp as well as other invasive species that might move from the Mississippi River basin into the lakes and vice versa.
The basin and the lakes are not naturally connected. Manmade alterations a century ago linked the two so that Chicago sewage would flow downstream instead of into Lake Michigan. Illinois politicians and barge companies now insist that those links are too vital to commercial navigation to be closed.
