Mitt Romney has made a bold choice by choosing Paul Ryan as his running mate. People will argue whether it's a good choice. But it basically will energize conservatives. The Tea Party loves Ryan. He's the most substantive of all the House members.

This choice gives the Republican Party someone who will go out and give us what the Republican plan will be for our economy, whether Romney wins or not. He was the architect of it.

He gives Romney the opportunity to go after young voters on fiscal issues. Saturday's announcement will make this a substantive campaign for the next couple of weeks. This is a guy who is not going to make mistakes. He knows the substance of the debate over our economic future better than anyone else.

He is the Jack Kemp of this generation. Kemp was the great creative architect of the Reagan tax cuts. He has the opportunity to do what Reagan didn't do. Reagan had the opportunity to pick Kemp, which he didn't do.
