The CNN exit polls explain the passage of Proposition 8, that eliminates the right of gays to marry in California:
African-Americans voted for Proposition 8 by a 69 percent to 31 percent margin. However, 55 percent of white voters and 52 percent of Hispanics voted against the proposition.
This does seem to affirm the common observation that African-Americans tend to be highly homophobic. It is unfortunate that a group that has been a traditional victim of discrimination voted yesterday to deny legal rights to another community.
