It's no secret that New Jersey's a blue state.

But according to a ranking by CrowdPac.com, it's also home to the second-most liberal city out of 4,994 communities ranked across the United States — Ridgefield Park.

Ridgefield Park ranked a "9.0L" on its scale, where 10L is the most liberal and 10C is the most conservative. The site says it ranked cities by collecting information on political donations on the federal and state level since 2002 for every community with a population of more than 6,000.

That still makes it less liberal than Vashon Island, Wash., with its 9.9L score.

No other New Jersey cities cracked the top 10 for most liberal or conservative communities.

So does the ranking play out?

Ridgefield is governed by a board of commissioners — formally a non-partisan body, so it makes it tough to suss out party preferences just from recent local elections.

But in 2012, Democrat Democrat Barack Obama received 3,162 votes in Ridgefield Park, ahead of Mitt Romney's 1,508. Obama was the favorite over McCain in 2008 with 3,256 to 1,932 votes as well.

And yet, in 2013, Republican Gov. Chris Christie still got more votes out of Ridgefield Park than Democrat Barbara Buono, 1,473 vs 1,138. Then again, the race was largely seen as a shoe-in for Christie throughout the state, and that was reflected in the numbers almost everywhere. Ridgefield Park picked Democrat Jon Corzine over Christie in 2009, 1,657 to 1,223 votes.

So how did some of New Jersey's biggest communities fare?
