The fight over Arizona's controversial immigration law has helped boost Gov. Jan Brewer's (R-Ariz.) standing among GOP voters, according to a new Rasmussen poll.

Brewer now ganers 61 percent support in a three-way GOP primary. That's up from 26 percent two months ago.

Beyond signing the bill into law, Brewer has engaged in a high-profile spat with the Obama administration over a potential lawsuit.

Brewer became governor when Janet Napolitano accepted a position as Homeland Security secretary. She has yet to be elected in her own right.

More from Rasmussen:

Brewer has had a remarkable surge in support since signing the state’s new immigration law and becoming a forceful national advocate of the measure despite criticism from President Obama, Mexican President Felipe Calderon and others.

Eighty-nine percent (89%) of GOP Primary voters support the immigration law, and 66% of those voters favor Brewer.

The 61% support for Brewer is up from 45% last month and 26% support the month before.

In March, before the health care law and immigration issues began to improve her standing, Brewer was in a virtual three-way tie for the nomination. She had drawn primary competition because of her unpopularity amidst the state’s budget problems.
