Republicans must also clean up their act on immigration, Mr. Bush insists. Last year, he says they “set a tone” that pushed Hispanic voters away. “The tone of the debate reached a point that was very damning to the Republican Party, and the evidence is in. The chest pounders lost.”

Mr. Bush supports immigration reform as championed by his brother and John McCain, which would allow illegals already in this country to stay. “Politics has to be about ideas and values and aspirations.” he says. “It shouldn’t be about anger and preying on people’s emotions. You can’t lead a mob.”
