Via The Hill:

Blue states slightly outnumbered red states in 2013 — however, the Democratic advantage has dropped from seven to three in the past year.

According to a Gallup poll, 17 states either lean or are solidly Democratic, while 14 states either lean or are solidly Republican. Nineteen states remain competitive, the same as 2012.

Democrats have long held an advantage in the Gallup poll, but the number has greatly diminished since 2008 when President Obama was first elected. That year, Democrats held a 30-state advantage, which dropped to a 12-state advantage in 2010.

Republicans gained three solidly Republican states in 2013 — including South Carolina, South Dakota and Oklahoma.

The numbers are based on Gallup polling done throughout 2013, and includes independents that lean either Republican or Democrat.
