Limbaugh is a Republican and makes the mistake of implying the Republican establishment is anything other than Democrat Lite. Boehner stripped Justin Amash and Tim Huelskamp of their membership on the Budget because they aren't "team players". Which means of course they know raising taxes is a HUGE mistake and are opposing the milquetoast leadership.
The truth is spending, out of control, insane spending is what the true issue is. Revenues or taxes are just fine.
