From the diaries. . .

Rick Santorum makes an excellent point that “past performance really does indicate future results.” I completely agree—but not just “in Mitt Romney’s case.” Rick Santorum became the third-highest ranking Republican in the Senate in 2001 at a time when Republicans inherited balanced budgets, surpluses, and conservative, pro-life majorities.  Senator Santorum and his big spending GOP allies proceeded to squander this inheritance.

The leadership of the Rick Santorum Republicans proved disastrous:

This is not a record of leadership to be proud of, and in 2006 it resulted in a catastrophic 18-point defeat. I fear it would do so again in the fall of 2012 if he were the nominee.

Unlike Senator Santorum, I did not go to Washington seeing politics as a “team sport.” Instead, I set out to change the game, and was willing to fight the forces of the establishment within the Republican Party to do so. The result was the first GOP majority in 40 years and the largest increase in pro-life votes in House of Representatives history. When I was Speaker, we balanced the budget for the first time since the 1920s — and it stayed balanced for four straight years. We reformed welfare, lifting millions of Americans from poverty. We passed the biggest capital gains tax cut in history, helping create 11 million jobs. And we did it all while paying down the national debt by $400 billion.

If you agree with Senator Santorum that “past performance really does indicate future results,” it means there’s only one candidate in this race who can offer the change our country desperately needs.
