Former Obama strategist: Partisan loyalty is the best explanation for why Trump is polling so well with his voters

Former Obama campaign strategist Joel Benenson said Wednesday that partisan loyalty to President TrumpDonald John TrumpTrump: I hope voters pay attention to Dem tactics amid Kavanaugh fight South Korea leader: North Korea agrees to take steps toward denuclearization Graham calls handling of Kavanaugh allegations 'a drive-by shooting' MORE is the best explanation for why the president continues to poll well with his political base, citing his popularity among white, evangelical voters.

"White, evangelicals have been the base of the Republican Party for more than a decade already. Probably closer to two decades. They are older, they are white, they are less likely to be college educated, and so they have been the base of the party," Benenson told Hill.TV's Joe Concha on "What America's Thinking." 

"He's [Trump] is a Republican. They're Republicans. It's when people say 'Oh, his base seems to stay with him,' of course they do," he continued. "So I think there's an element there that is just how they've been voting, and they're going to stand by their candidates. They're not voting on their religious, moral principals for sure based on this," he said. 

While various polling shows Trump's approval rating sitting around 40 percent, he remains popular among his base. 

Ninety percent of Republicans said they approved of Trump's job, according to an NBC News/Wall Street Journal poll released late last month.

Trump's approval rating is also high among white, evangelicals who have shown loyalty to the president throughout his term.

In April, the Public Religion Research Institute (PRRI) found that Trump holds a 75 percent favorability rating with white evangelicals.
