In a letter to supporters, Rick Santorum reportedly wrote that he is "considering putting my name in for the 2012 presidential race," citing concerns over President Obama's purported "single-minded pursuit of a radical domestic agenda" and that "the Obama Administration buried its head in the sand and has turned a blind eye towards several major threats to our country."  From the letter:

You see, two years ago, candidate-Barack Obama sold our country a false bill of goods.

And now we're paying a heavy, heavy price.

Enough is enough.

That's why I hope you'll join me today to lay the groundwork for taking back our country.

I promise you, I will stop at nothing when it comes to defending our freedom and our values.

That's the real reason why - after talking it over with my wife Karen and our kids - I am considering putting my name in for the 2012 presidential race.

And I'd like to know what you think about this - so please share your thoughts by rushing the attached "2010 Launch" reply back to me right away!

Rick Santorum is a Fox News contributor.  In August, Fox & Friendstouted former Senator Santorum - who suffered a "landslide defeat by Democrat Bob Casey" in 2006 - as a 2012 presidential prospect. Fox News personalities Mike Huckabee, Newt Gingrich and Sarah Palin are also considering 2012 runs.
