Excerpt: Rhode Island and Massachusetts -- along with the District of Columbia -- were the most Democratic U.S. states in 2009, based on their residents' stated political affiliations. Wyoming and Utah ranked as the two most Republican states in the nation.
These results are based on aggregated data from Gallup Daily tracking in 2009, including interviews with more than 350,000 adults in all 50 states plus the District of Columbia. Gallup conducted at least 1,000 interviews in every state except Wyoming (878), North Dakota (968), Delaware (997), and the District of Columbia (632). Gallup interviewed more than 20,000 residents each in California, Texas, New York, and Pennsylvania.
Nationwide, party support shifted in a slightly more Republican direction in 2009 after a historically strong Democratic year in 2008. Overall, 49% of Americans in 2009 identified as Democrats or said they were independent but leaned to the Democratic Party, while 41% identified as Republicans or were Republican-leaning independents. That 8-point Democratic advantage compares to a 12-point, 52% to 40%, Democratic advantage in 2008.
