Dewhurst is the clear choice among registered lobbyists in Texas, drawing 26 times more money from them than Cruz, according to a recent analysis of campaign finance data by the Houston Chronicle. Lobbyists in Washington, D.C., are donating to the race on a smaller scale but favor Cruz, according to the same analysis.
Dewhurst attracted $189,869 from 85 registered lobbyists in Texas, while just four Texas lobbyists gave a combined $11,750 to Cruz, according to the report. Federal lobbyists and their families have donated $120,148 to Cruz. Dewhurst has drawn less than $25,000 from that sector.
