Donald Trump is no longer the most extreme GOP candidate on immigration.

While Donald Trump’s calls for a Mexican border wall and the deportation of 11 million undocumented immigrants have galvanized his campaign, the real estate mogul is now a moderate compared to Texas Senator Ted Cruz. As reported by BuzzFeed’s Andrew Kaczynski, Cruz on the campaign trail in Iowa had the following eye-popping exchange with a voter:

QUESTIONER: Both you and Donald Trump are really strong on immigration, but he supports deporting all the illegal immigrants. Are you willing to say the same?

TED CRUZ: Absolutely, yes. We should enforce the law.

Q: All?

T.C.: We should enforce the law.

Q: OK.

T.C.: And in fact, look, there’s a difference. He’s advocated allowing folks to come back in and become citizens. I oppose that.

To deport 11 million people and give them no way to return to the country they once lived in would amount to one of the biggest forced migrations in human history. Some pundits worried that Trump would make right-wing Republicans like Ted Cruz look moderate, but before the campaign is over it could turn out that Trump is too moderate for the GOP.
