(Paraphrased as needed)
1. We admit our party led us astray from reality.
2. We admit there is a power greater than the GOP
3. Make a decision to make up your own mind
4. We admit what we believed was wrong.
5. Make amends to our progressive or minority friends we have harmed or spoken poorly of.
6. Take a personal inventory of our thinking and be prepared to admit where we were wrong and act on it.
7. We seek truth through fact gathering and exhibit a first loyalty to facts.
8. Have a political awakening and encourage Republicans to stop what they are doing and seek the truth with us.
