Cruz has had success raising money from both a robust base of grass-roots supporters and a substantial network of rich backers – a formula that has continued as the Republican race has narrowed and wealthy donors who supported other candidates are turning to – or in some cases softening on – Cruz.

According to the campaign, it has now raised more than $78 million over the course of the campaign, which kicked off last March, from more than 450,000 donors. The average donation is $52 – lower than what it had been over the past few months.
