Ex-Florida Gov. Jeb Bush and former RNC chief Ken Mehlman pen a Wall Street Journal op-ed in support of the Senate immigration bill. "Both of us have spent much of our professional lives working to help build the Republican Party. We believe this legislation will be good for the GOP. Hispanic Americans are natural Republicans. Many tend to be pro-life, pro-military and pro-small business… The immigration reform before Congress is far from perfect; it's a compromise after all. But, on balance, we are convinced that this legislation is the right choice. It represents progress in making America safer and stronger; progress in making our economy more competitive and flexible; progress in reinforcing the rule of law and progress in the important work of national unity. Doing nothing is not an option."
