Are you voting in the 2016 presidential election? Both the Iowa Caucus and New Hampshire Primary have truly demonstrated how every single vote counts. In Iowa, Senator Bernie Sanders and Secretary of State Hillary Clinton were in a “virtual tie” with only .29 percent separating their margins — with the “apparent winner” being Hillary Clinton. While in New Hampshire, three out of the eight Republicans were in a dead heat — only separated by a couple of basis points from one another.

However, there are still 48 states and millions of Americans who can change the course of the presidential race. If want to make sure your vote is heard, now’s the time to make sure you’re well prepared with the right information: Does my state party hold a primary or a caucus? What is the voter registration deadline? When is my state primary held?

Here is a list of the 50 states and the important information that you need to participate in the presidential primary or caucus election (dates vary by state) and the presidential general election on November 8, 2016 for all 50 states.

Please note that most of these voter registration deadlines are for first-time unregistered voters. If you’re changing party affiliation or updating your information, the deadlines may differ. Since certain dates may be subject to change, it’s very important to contact your state party for more information.
