1) Drop out of the primaries earlier rather than later.
Throw your support to a Conservative & work from the sidelines in a kingmaker role.
2) Deny that Romneycare is a success. Renounce it plain and simple in no uncertain terms.
“I was wrong, but I did what has been proved to be wrong because I thought at the time that it was the right thing to do. I'm sorry.”
3) Work in your strong states to get out the vote and counter Democrat talking points at every turn.
Be public. Be firm.
That's the only way that you will avoid becoming a footnote in American political history.
I will agree with you about this.
