You said... “retention”... a loaded word for this topic.
Would you prefer that your elected representatives in Washington, DC (ROTATED) vote to overturn the 1993 law and allow homosexual persons to serve openly in the military, OR vote to keep the law as it is? 48% VOTE TO KEEP IT AS IT IS 45% VOTE TO OVERTURN 7% DO NOT KNOW/DEPENDS (VOLUNTEERED) 1% REFUSED (VOLUNTEERED) Margin of Error 3.1% at 95% CI
In other words, no conclusion can be drawn about whether a plurality prefer to keep the law or overturn it. The difference is within the margin of error. There's some push in this poll, too. The loaded questions at the start of the survey link DADT to several unobjectionable statements about the military, biasing the respondents against repeal of DADT. It's subtle, but it's there.
