"He came back for two months in the summer and then he moved to an apartment," Hobbs said. "He considers himself a Tempe resident. He's not planning to come back to our house."

Hobbs said it makes no sense to treat all students as temporary residents of their college communities based simply on "what you think is going to happen."

Thorpe said he's open to listening to any arguments that Hobbs has about the wording of the measure to ensure that students do not get disenfranchised.

"I want them to vote," he said, but on issues that he believes affects their friends and parents. "For them to be in a community part-time and change the dynamics of a local election for people who live here 12 months out of the year and they're only living here part-time, I think that's really unfair philosophically."

Ditto, he said, on part-year residents.

"I think it's just as bad for them to vote in Arizona (as it is) for a kid that lives in Tucson but is going to school for five months, six months out of the year in Flagstaff," Thorpe said. "I think the snowbird should be voting in Minnesota and the kid from Tucson should be voting in Tucson."
