WASHINGTON - It bothers Brian Gronquist that he can vote at his precinct in Andover, just like anywhere else in Minnesota, and not show any photo ID.
"I could be anybody," said the Anoka County businessman.
Increasingly, the act of voting, taken for granted by the majority of nonvoters, is becoming a battleground issue nationwide.
This week, as the presidential campaign picks up momentum, the U.S. Supreme Court will hear an Indiana voter ID case that divides opinion largely along partisan lines -- and puts a pair of Minnesotans in the national spotlight.
One is Rep. Keith Ellison, a Democrat who has helped challenge Indiana's new photo ID requirements as an "unconstitutional poll tax" that discriminates against minorities.
The other is former Minnesota Secretary of State Mary Kiffmeyer, a Republican who has testified in Congress in favor of photo ID requirements, which she says are essential to the integrity of the democratic process.
Not since the 2000 presidential election, which was decided by a few hundred votes in Florida, have the two major parties put so much effort into the mechanics of who can vote and who can't.
"The very closeness of elections ... is making this much more pressing of an issue," said Hamline University Prof. David Schultz, who teaches election law at the University of Minnesota Law School.
