"The Iraq war got them their power;"
That door swings both ways.
The Repugs started in the Iraq war as the "immediate and only option" to get dubya elected. "immediate" because they had to start to war in March and give it enough time to become"Mission Accomplished" well before the Nov 2003 election. dubya won as the "war president" in 2003 with the smallest margin ever for a winning in bent president.
With no Iraq war, there was a much better chance of dubya getting kicked out after 1 term, like his father.
