Lieberman defends Bachmann and Perry for talking about their Christianity on the trail

"They don’t lose that right under the Constitution just because they become a candidate for public office," continued Lieberman. "The second thing is this is the history of our country, our country was founded on religious faith.”

Lieberman, who was a Democratic vice presidential candidate in the 2000 election, is a devout orthodox Jew, and recently wrote a book that prominently featured his faith titled The Gift of Rest.
