Would there be a Republican pledge without the Tea Party movement?

In 18 months the Tea Party went from zero to 29% of the voters. What would Republicans be pledging or debating if it weren't for these folks nipping at their heels as they turned tail and ran?

Highlights of the Pledge include:

1. Small business income deduction of 20% of income
   
2. Permanent extension of current tax rates to avoid largest tax hike in history
   
3. Cancel unspent stimulus funds
   
4. Place a cap on all new discretionary spending
   
5. Restore spending to pre-stimulus, pre-bailout levels of 2008
   
6. Repeal and replace the health care law
