Romney-backing Super PAC drops 30-second TV spot in Arizona, Michigan and Ohio targeting Santorum.

Script: “Rick Santorum – Big spender, Washington insider.”

Read the script below.

SCRIPT: “How did Rick Santorum actually vote? Santorum voted to raise the debt limit 5 times. And for billions in wasteful projects including the “Bridge To Nowhere”. In a single session, Santorum co-sponsored 51 bills to increase spending and 0 to cut spending. Santorum even voted to raise his own pay. And joined Hilary Clinton to let convicted felons vote. Rick Santorum – Big spender, Washington insider.”
