I placed "gayest" in quotation marks because the poll relies on people's willingness to self-identify as gay; particularly on this issue, polling is a highly inexact science.
Still, the results are interesting.
LGBT Percentage Highest in D.C., Lowest in North Dakota
The poll question, "Do you personally identify as lesbian, gay, bisexual, or transgender" was answered Yes by the following percentages (top 10 jurisdictions):
District of Columbia, 10%
Hawaii, 5.1%
Vermont, 4.9%
Oregon, 4.9%
Maine, 4.8%
Rhode Island, 4.5%
Massachusetts, 4.4%
South Dakota, 4.4%
Nevada, 4.2%
California, 4.0%
Personally, I'm surprised that South Dakota and Nevada both scored ahead of California.
