Any adult should have learnt that starting with a kernel of truth, or flooding the debate with accusations and demands, are effective methods to mislead and deceive people. It is a proven method for suppressing facts. It lacks integrity, and serves the goals of the corrupt.
It is strange to me that people perfectly aligned to the attack lines of corrupt politicians (in your case, the Republican flavour) bother pretending even to themselves that it is the corruption that really bothers them.
