On Sunday, CBS’s “Face the Nation” interviewed Sen. Jeff Flake of Arizona about Republican presidential nominee Donald Trump possibly losing Flake’s home state to his opponent Democratic nominee Hillary Clinton in the general election.

Below is Flake’s response:

DICKERSON: You mentioned Arizona and some of the effects of what Mr. Trump said on voters in that state. Is there any chance that Hillary Clinton could win in Arizona?

FLAKE: In 1996 Bill Clinton won in Arizona, so it’s possible. Hispanic population here is about 33%. The voting population of Hispanics isn’t as large, but it’s growing. And the poll shows increased urgency among Hispanics to vote. If they do, it will be a changed ballgame here. We in Arizona realize that we have to have meaningful immigration reform. You can’t just throw platitudes out about a wall or Mexico paying for it and be taken seriously here. I think yes, he does have to change his positions and be a more serious candidate.
