A Gallup poll measures the level of conservatism and liberalism of American states, as judged by those who are questioned about their perception of politics.
Under this measurement, the order of the top ten conservative states are Mississippi, Idaho, Alabama, Wyoming, Utah, South Dakota, Louisiana, North Dakota, South Carolina, and Arkansas.
Note that this is a list of five Southern states, two Great Plains States, and three Mountain West states (which happen to have large percentages of Mormons in their population).
The ten most liberal states are, in order, Vermont, Rhode Island, Massachusetts, Connecticut, New York, Oregon, Colorado, Washington, New Jersey, and California.
Note that this is a list of four New England states, two Middle Atlantic states, and four Western states.
So the country is still very much a divided country ideologically, and in many respects, by geographic section!
