All things shall pass, the saying goes, unless, perhaps, you are a Republican Congressman voting on the Emergency Economic Stabilization Act of 2008.   In a quite unexpected turnaround yesterday, the US House of Representatives rejected by 228 votes to 205 the $700 billion rescue package that the top brains from the Treasury, the Federal Reserve, the administration and both political parties had spent the latter half of last week and the whole weekend thrashing into a workable compromise.   It was a shocking decision, in more ways than one.
