Republican presidential candidate Newt Gingrich has made lists of his donors and supporters available for rental – while still conducting his campaign. While campaigns do at times offer their donor files for rental, standard practice is to wait until the campaign is over.

But the Gingrich campaign has been financially strapped for a while. On April 8, Gingrich revealed that his campaign was carrying $4.5 million in debt. And recently it bounced a $500 check that was supposed to cover ballot access fees for the June 26 Utah primary (Gingrich has until April 20 to make good on the check).

Gingrich made his donor lists available for rental on April 11, according to Mike Murray, president and CEO of list firm TMA Direct, which is managing the files. Murray would not speculate on whether there was precedent for an ongoing campaign making its lists available.
