Gary Welsh of Advance Indiana has called attention to a study recently released which tallies the percentage of our population that self-identifies as glbt. Self identification can be an incomplete concept, because many who have a biologic same sex orientation will not identify themselves as gay, in spite of their physical and emotional attraction to the same sex, especially if they come from a conservative environment in which they are taught to be uncomfortable with the reality of their biologic orientation. This data is broken down by congressional district.
As Gary observes, the percentage of gays in Central Indiana is estimated to be 4.5% or so of the population, 4.8% in Indianapolis.
That's almost 1 in every 20 voters.
Consider this: With some few exceptions, the average person can list a natural father and a natural mother and some statistical fraction of a sibling, and gays and lesbians are no different. So to 1 in every 20, add 2 in every 20 representing parents who have given birth to a gay or lesbian child, and another 1 (or so) representing a sibling of a gay or lesbian child. That's 4 in 20, or 20%, of voters who have a vested family interest in the treatment of gays and lesbians. Throw in another 1 or 2 (5 or 10%) representing friends, and then classmates and work colleagues (what... 8 or so for every gay person?)
