The air war is heating up in the battle over Minnesota's election system.

Supporters and opponents of a proposed photo ID constitutional amendment unveiled new television ads on Friday. The amendment will appear on the Nov. 6 general election ballot.

An ad from ProtectMyVote.com, which supports the amendment, shows various people -- a construction worker, a farmer, a military veteran -- talking about the importance of "one vote."

The script reads: "When someone cheats, they cheat you out of your right to be heard." The group said the ad will begin running on statewide broadcast television on Saturday.

A television spot from Our Vote Our Future, which opposes the amendment, features current DFL Gov. Mark Dayton and former Republican Gov. Arne Carlson, each opposing the measure. The present and former governor say the amendment is too costly, will prevent many seniors from voting, and "basically ends same-day registration."

Our Vote Our Future said the ad began running statewide on Friday.
