In 2008 almost 2 million Americans failed to vote simply because they did not know where to go. That’s part of the reason why the Pew Center for the States and Google teamed up to develop an application that makes it as easy as possible for voters.

It’s the second year the application has been available to Connecticut voters.

This year it may be even more important for Connecticut voters to enter their home address into the application because many polling places may have changed as a result of redistricting. Voters should have been notified of the change in polling location, but there have been some glitches like in New Haven where Republicans were told to vote in the Democratic primary, while others were given the wrong polling location.

Gov. Dannel P. Malloy, who resides at 990 Prospect Avenue in Hartford, voted at the Annie Fisher School last year, but will vote at the Hartford Seminary Tuesday because of the redrawn political lines in the city’s General Assembly district.

There were an estimated 850 polling places throughout the state two years ago, but municipalities took redistricting as an opportunity to consolidate some voting districts into other polling locations.

“In many cases polling places may change, not necessarily shrink in number,” Secretary of the State Denise Merrill said Monday.

Merrill is hoping more voters decide to use the web application instead of calling her office to find their polling place. She said people are often confused about whether they can vote and whether they’re registered.

Voters can plug their location into the application embedded above in order to find out their polling location. If it doesn’t show up on the map immediately you can click the details button and it will give you the address of the polling location.

However, there’s also a web application for that. Voters can put their information in here to find out whether they are registered and only those who are registered with the Democratic or Republican party will be able to vote in Tuesday’s primary.

Those who do have problems at the poll should call the hotline at 1-866-733-2463 or send an to election officials. Both will be monitored throughout the day by staff from the Secretary of the State’s office and the State Elections Enforcement Office.

“We’re trying to get a handle of situations before they occur,” Merrill said Monday.

Merrill will be going around the state to various polling locations Tuesday to make sure things are going smoothly. She said she has some concerns about how things will be handled in places where the Registrar’s of Voters are on the ballot themselves.

Merrill is predicting about 30 percent voter turnout statewide. The numbers may be higher in places where there are contentious battles like in the 5th District where there are three Democrats and four Republicans on the ballot.

“In primary elections, it really depends on the heat of the election,” Merrill said. “That seems to be true across the years.”

There are a total of 1,137,580 registered Democrats and Republicans eligible to cast a ballot Tuesday for offices such as U.S. Senator, Representative in Congress, General Assembly, Registrar of Voters, and Judge of Probate.
