2003 - 2004 was a profile in cowardice.
Cheney, Rumsfeld, and Wolfowitz timed an Iraq War Resolution for October 2003. Dem Senators that had ambitions for running for President in 2004 and 2008 voted for it, because they didn't want to look weak on the War on Terror.
Dem President-wannabes, John Kerry and Hillary Clinton, went along with Bush '43 lies. They abandoned their responsibility to act as check and balance against unncessary Executive wars of foreign adventure to their ambitions to become President. They did the next wrong thing out of self-interest, that cost America in blood, treasury, and lost opportunities.
Ted Kennedy voted against the Iraq War Resolution on principle. I didn't agree with Ted Kennedy's policies, but he was a man of principles (that I disagreed with) and of the people (Ted helped many average Joe's while John Kerry did nothing useful).
The Republican Party of 2004 lied to the American People and to the World, to start a war of choice against Saddam Hussein, and labeled opponents "RINO's".
The Republican Party of 2004 grew Government spending, not reduced it. Again, detractors were labeled "RINO's".
The Republican Party of 2004 enacted Medicare Part D, without the ability to negotiate prices. Again, detractors were labeled RINO's.
So, in 2004, if you were for smaller government, less spending, and against nation building, you became a RINO.
The GOP of 2004 never should have existed because it was not enacting conservative policies.
