Instead of ignoring or belittling the conservative media, Rubio enthusiastically engaged then with respect and candor. Ultimately, I think he made some promises during these interviews that may hurt his credibility down the road, but I do not believe he ever intended to deceive. If anything, the legislation he was able to produce with Democrats probably fell short of what he originally thought it would look like.

Throughout the debate, Rubio never impugned the motivations or character of his opponents. Instead, he often praised them for trying to make the bill better. This stands in stark contrast to Republican leaders of past immigration reform efforts. And when wayward staff, or other supposedly conservative allies, did disparage amnesty opponents, Rubio either admonished them or distanced himself from the attacks.

The immigration debate is far from over this year. In fact, it probably is only halftime. But so far, the debate has been far more civil and productive than it was in 2006 or 2007. Rubio’s exemplary leadership on this issue is a big reason why.
