Burgum, in order to meet the donor threshold set by the Republican National Committee, offered donors $20 gift cards for $1 donations. The first debate required candidates to collect 40,000 individual donors, with at least 200 unique donors per state, as well as poll at 1% in three RNC-sanctioned polls, or 1% in two other national polls and two polls from key states.
