A presidential campaign bid, even a failed one, can open doors to lucrative career options, such as former Arkansas Governor Mike Huckabee’s Fox News contract.

In the case of Newt Gingrich, a financial comeback may be a harder climb.

The former U.S. House speaker’s time on the campaign trail has led to the shuttering of two businesses that generated $107 million in income during the last 10 years and helped him accrue at least $7.3 million in assets. His campaign also is struggling, bouncing a $500 check for the filing fee in the June 26 Utah primary, and amassing almost $4.5 million in debt.
