Gallup has some good data out this morning, with a look at President Obama's approval rating in each of the 50 states (plus the District of Columbia).

It should be noted at the outset, however, that the polling data is based on telephone interviews from January 21 through June 30. His numbers have slipped steadily since then.

For what it's worth, though, Obama polled best in DC -- 92 percent approve. His lowest approval rating is in Wyoming, where just 46 percent approve.

From Gallup:

In general, state patterns of support for Obama follow the political orientations of the states. For the most part, the states that Gallup classified as "solidly Democratic" (based on the party affiliation and leaning of its residents in the first half of the year) had approval ratings at or above the national average of 63%. The four states Gallup identified as being "solidly Republican" -- Wyoming, Alaska, Utah, and Idaho -- gave Obama his lowest average approval ratings. But even in these four states, his approval rating exceeded his disapproval rating.

Some other nuggets:
Highest Red State Approval: North Dakota (63%)
Highest Red State Net Approval: Missouri (+33)
Lowest Blue State Approval: Colorado (55%)
Lowest Blue State Net Approval: Colorado (+22)
