Tis the case with political affiliations. Who's a democrat??, whose a republican??, etc.
A lot of democrats vote and call themselves republicans. They seem to pick up on one or few items and ignore the rest. The republicans play this issue because of numbers and then generally let the issue fade once in office.
A republican is a wasp, rich and wants government out of his business.
A democrat is a minority, not rich and wants some government assistance.
I remember, back home, we had one constable for the county [on the republican ticket]. Republicans felt that one was enough. They didn't want his plaquered ford station wagon going in front of their homes. So they convinced Democrats to vote Republican; that way the democrats would not have to pick up their routy kids after a Friday night melee followng the high-school foot ball games. However, when they really needed help, he was busy catching kids. Nevermind the republicans, they had their gated sub-division with roads a maze, and culdesacs.
Really for both parties and members it's good to know who you really are...
