In front of a spirited crowd that packed the Tampa Times Forum, Chris Christie gave a solid speech which echoed Mitt Romney's programs consisting of substantial budget cuts, tax cuts, and entitlement reform.

Christie pressed on the notion of what he called “principled compromise,” which is exactly how I think Mitt Romney is going to proceed if he wins the election. In a very sharp dig at President Barack Obama, Christie emphasized true leadership, and not just governing in accordance with how the polls went. His line of the "Second American Century" — which is a Marco Rubio line — is a fabulous line. Basically, he means we are not going into decline.

This particular passage from Christie's speech caught my attention: "They said it was impossible — this is what they told me — to cut taxes in a state where taxes were raised 115 times in the eight years before I became governor. That it was impossible to balance a budget at the same time with an $11 billion deficit. But three years later, we have three balanced budgets in a row with lower taxes. We did it." He is saying you CAN reduce taxes and you CAN reduce spending, and you CAN grow the economy, and you CAN have a balanced budget; and that's been done before, in New Jersey. It's a prediction of what Mitt Romney is going to do.

I don't think he did as good a job of setting the table as Ann Romney, who was the star of the night. She gave a brilliant speech about her life with Mitt Romney, about their love, about their lives, and about how they grew up without a silver spoon in their mouth. She described her empathy, and her work with those less fortunate. Her description of Mitt as "[the man who] will not fail" was a terrific line.

I must confess, Ann Romney stole the show.
