It's a sign of political ignorance and very juvenile behavior.
But that's just me....
I suppose that on a advocacy forum like this, one would expect to find a lot of single issue voters, but it is a dangerous thing to do, and is easily manipulated by any group wishing to disrupt election outcomes.
The Rudy Rooters are text book "single issue" voters -- the ONLY thing they seem to care about is the war on terror. Now, this would be important if Rudy was the only GOP candidate supporting the war, but he isn't.
