The presidential campaign of Sen. Ted Cruz (R-Tex.) has raised more than $19 million this quarter as he is riding momentum heading into the nation's first voting contests.
In a memo to staff, campaign manager Jeff Roe said the campaign has raised more than $45 million since its launch in March. The campaign has received more than 670,000 donations from over 300,000 donors.
"Since launching the campaign at Liberty University on March 23rd of this year, we've built the type of organization it will take to win," Roe wrote.
Cruz has even more money backing him: a constellation of super PACs supporting the Texas Republican have raised $38 million as of June 30 -- and they likely have raised much more since then.
Cruz's campaign has found a formula no other Republican candidate has been able to match: a robust mix of grass-roots fundraisers and wealthy donors. Last quarter he had more cash on hand than any other Republican presidential candidate.
Cruz's average campaign contribution during the fourth quarter was $67, underscoring the importance of small-dollar fundraising to the campaign. But he is also doing very well with higher-dollar donors; last quarter he raised $5.2 million from supporters who gave him the $2,700 maximum — No. 2 in the GOP race for large donors, after former Florida governor Jeb Bush, according to an analysis by the nonpartisan Campaign Finance Institute.
Official fundraising reports do not need to be released until Jan. 31.
Roe's memo, which was first reported by The Wall Street Journal, said that the campaign's donors come from two-thirds of the zip codes in the United States. More than 10,000 donors are set up to give on a monthly, recurring basis -- the way a gym membership or utility bill is automatically deducted from a credit card each month. Those people provide about $500,000 each month, Roe wrote, an amount he said is enough "to fund for our entire field operation."
Cruz has ascended in the polls of late, something the campaign touted in the emails, citing polls showing him atop the field in Iowa, and a CNN poll showing him besting Hillary Clinton.
The campaign has sought to build a nationwide grass-roots coalition to support Cruz, and offered evidence, stating it has 1,400 people on leadership teams in 19 states. It said it has county chairmen in all 171 counties in the nation's first four voting states and has 175,000 volunteers lined up around the country. Roe said many of them will be deployed to Iowa and New Hampshire ahead of the caucus and primary.
"Some campaigns are focused solely on a man, some on a movement. Ours is a hybrid of the two built to win," Roe wrote. "This is OUR time."
