Gallup’s latest State of the States poll, published on Jan. 31, 2014, ranked each state in America from most conservative to most liberal.

While the gap between “conservative and liberal self-identification” is narrowing, the conservative advantage is still appears predominant.

According to the poll's data, most of the conservative states are found in the South and West, while the more liberal-identified states are located on the coasts.

According to Gallup, the results of the poll are based on phone interviews of 178,527 adults conducted Jan. 2-Dec. 29, 2013.
