Should We Blame President Lyndon Johnson For The Bridge Collapse?

As I wrote in the aftermath of the I-35W bridge collapse in Minneapolis, the Democrats were beginning to blame President Bush. I also noted that the bridge may have not been built to handle the capacity of 2007 traffic.
Well, I may have been right on the second point http://FoxNews.com. So, the question is, should we dig former President Lyndon Johnson out of the grave and blame him for the bridge collapse? After all, since the modern Democrat party was blaming President Bush as they do for all wrong, or even right, in the world, since the I-35W bridge was built in 1967, lets blame Mr. Johnson!
I am being somewhat facetious, but you get the point. Before bodies were pulled out of the wreckage, far-left Democrats starting with Minnesota's junior senator, Amy Klobachar, were quick to slam President Bush. It was pointless and dumb. But, by golly, that never seems to stop the Democrats.
The point is that people should have cooled their jets and let the investigation begin and run it's course. Politicians need to stop blaming and let the process take course. A simple fact is that someone with no understanding of the nuances of bridges as myself deducted that it was possible the design of the bridge may be the culprit.
Here is a deal. I won't blame former President Johnson if the Democrats suffering BDS, Bush Derangement Syndrome, stop blaming President Bush? See how easy life would be!
