They might not be voting Democrat, but enough of them opposed Bush's social security reform to kill it. As we have learned especially since Bush Sr. raised taxes, being an "R" doesn't mean you always support the right policy. The country needs to get behind any given policy and the way SS reforms were blocked under Bush was unconscionable.
If you want a conservative policy implemented, then work on your democrat voting age group, and direct less criticism at the conservative voting age group.
Rather than promoting raising the tax burden on the poor, you should be working to lower taxes on the better off.
