Voter ID laws in all 50 states — in 1 map

With only 40(!) days left before the Nov. 6 election -- and many states having already begun early voting -- the long-running debate between the parties about voter identification laws in the state is heating to a boil.

Democrats insist that the push by Republican state legislatures and governors for stricter voter ID laws amounts to a not-so-subtle attempt at suppressing the vote among key Democratic constituencies.  Republicans retort that their sole aim is to ensure that the vote on election day is fair for everyone -- regardless of party.

Spin aside, it's worth simply going through what states have what laws currently. And, thankfully the National Conference of State Legislatures has put together a national map that does just that.

That map is below. States in green -- more of a mint, actually -- have strict photo ID laws on the books while those in yellow have less strict photo ID requirements. States in blue have non-photo voter ID laws while those in gray have no voter ID law on the books.
