But groups supporting stronger immigration policy and tighter border control say they rely more on small donations from individuals than large foundations.

Numbers USA, which says it has 366,000 members, saw its membership grow 50 percent since Jan. 1, and 18 percent in May, spokeswoman Caroline Espinosa said. Two-thirds of the group's financial support comes from private individuals, with the average donation being $40.

"Contrary to what might be popular belief is that the grass-roots aspect is more on our side than the [pro-immmigration] side," Mrs. Espinosa said. "They have more of these organized, established types of groups founding them and driving their activism."
