Long lines are being seen at polling places in swing states across the country as Election Day 2016 has finally arrived.

While every vote is important, there are some states that seem to always get the most attention when they are classified as a swing state, or a state that can swing an election.

Most of those states have large Electoral College vote counts, but that’s not always the case. Some are more important to the strategy of busting up the opponents ‘firewall” of states or states considered safely in a candidate’s victory column.

With an election where nothing seems predictable, both Republican Donald Trump and Democrat Hillary Clinton have campaigned in the traditional battleground  states, but they are also showing up in states where, traditionally, their party’s candidates don’t spend much time.

Here’s a look at some of the 2016 swing states, what makes them important in this race, and the latest election information from and about them.
