Because it challenges the "Good ole boy network".
Anybody who does not goose-step to and lick the boot leather of the 'Good ole Boys' are treated like the unwashed masses. How DARE you question those that do all the work? How DARE you challenge your ELECTED OFFICIALS?

You know, the old, "Rules for thee, but not for me" line of thinking.

The 'Good old Boy network' cannot see the forest for the trees, they have licked enough boot leather that they can only advocate for themselves, the lower-class minions can't speak until they learn the secret handshake, or have earned the secret decoder ring....
