As long as the Cruz presidential committee has money–and it has more than $6.3 million now–it must return your donation, if you ask for it.

Note the amount of your toal donation, and send your letter
return-receipt-requested. If you have a receipt from Cruz, send a copy.
If you have better uses for your own money than Ted, waste no time.
He could transfer some or all of it to his 2018 senate reelection
