Does it go back to his political party? Please provide a source or fact, not your opinion.What happens to campaign contributions once a candidate drops out?
There is limited options to what you can do with leftover campaign cash.





1) You can keep it in a federal campaign account and use it to run for federal office later.





2) Give the money to another federal campaign. I.e. Ron Paul could donate the money ot somebody else running for federal office.





3) Give it to a party committee.
