The poll, conducted by John McLaughlin of McLaughlin & Associates between May 27 and May 28 found Cantor with 62 percent to Brat with 28 percent, according to The Washington Post on Friday.
Cantor lost to Brat on Tuesday. With 90 percent of precincts reporting Brat defeated Cantor 55.4 percent to 44.6 percent. It was perhaps the biggest upset of any primary contest in the 2014 election cycle.
Brat ran a tea party challenge against Cantor focused on immigration. But Brat's candidacy didn't get much national attention or attention from the most prominent outside groups that have boosted conservative challenges to incumbent Republican lawmakers.
