Catch 22

This defies logic:

I've made the observation in the past that high income voters are overwhelmingly in support of higher taxes and Democrats--as the 2004 pre-election polls showed. One of the reasons that Republicans can't hold onto power is that their policies promoting economic growth and low income tax rates--especially in the higher brackets--end up creating vast swarms of highly paid, undertaxed voters--who reward Republicans for this by voting Democratic. Democrats can't hold onto power because their tax policies wipe out many of these highly paid, undertaxed voters--and middle class voters (those making under $100,000 a year) start to predominate again.
