About half the people don't pay income taxes because of deductions and tax credits. You're saying none of them vote Republican? Because I doubt they will if the Republicans run on a platform promising to raise their taxes. Would you?
I've benefited from various deductions in the past too, but I still can see the effect on our society of a tax system which punishes the workers and encourages the parasites. I like the idea of somehow making the tax system better and I like that someone has enough backbone to raise the topic.
