This was a tape of a 4 year old speech that Drudge distorted and sensationalized. This was not something Santorum said recently.
Santorum doesn't need to “give it a rest”. He is speaking out forcefully and clearly on a number of topics including the economy, environmental extremism, reducing government spending. Don't be fooled by the narrative put out by the MSM.
No one is fooled, we can think, read and google. Santorum has spent the past two weeks preaching. It seems like he is very interested in religion so why doesn’t he run for say, POTUS?
