INDIANAPOLIS -- A recent redrawing of Marion County's voting precincts is bound to have some people wondering where to vote in Tuesday's special election for the successor to the late U.S. Rep. Julia Carson.

Throw in the fact that not every county resident will get to vote -- the 7th Congressional District comprises most, but not all, of Marion County -- and the unfamiliarity of going to the polls in March, and you've got election officials bracing for all kinds of voter confusion.

"Frankly, it's kind of the perfect storm of voter frustration," county Clerk Beth White said.

Hoping to shepherd whoever needs help, the clerk's office says people can call 317-327-8683 to ask questions about the election or where to vote. People also can find their polling place at this Web site.

A map of the 7th Congressional District can be found here.

Running in Marion County's first-ever special congressional election are: Carson's grandson, Andre Carson, a Democrat; state Rep. Jon Elrod, R-Indianapolis; and Sean Shepard, a Libertarian.

The county recently reduced its number of voting precincts from 917 to 590 to make the staffing of elections more manageable. This means a voter's polling place may have changed.

Polls will be open Tuesday from 6 a.m. to 6 p.m.

Julia Carson died in December after a battle with cancer.
