Newt Gingrich's campaign sent out an email touting former Texas Solicitor General Ted Cruz's (R) Senate campaign Tuesday afternoon — but Gingrich himself is staying neutral in the race, a spokesman told The Hill.

Gingrich has been renting out his email list to outside vendors in order to help pay down his sizeable debt from the presidential campaign. This email comes from the Senate Conservatives Fund, a group backed by Sen. Jim DeMint (R-S.C.) and has long been in Cruz's corner in his race against Texas Lt. Gov. David Dewhurst (R). The email describes Dewhurst a "deal-making moderate" and "not someone who should be elected to the U.S. Senate."

While the email says at the top that it "reflects the opinions and representations of our advertiser alone, and not necessarily the opinion or editorial positions of the Newt 2012 campaign," the email does not say whether Gingrich agrees with the message or not. When asked if he was staying neutral in the race or if he agreed with his advertiser and backed Cruz, Gingrich spokesman R.C. Hammond emailed back a quick reply: "Yes — neutral."

The email shows the tough position Gingrich is in: in order to help pay down his campaign debt, he's had to give up control of a prominent part of his brand.
