The possible repeal of 'Don't Ask, Don't Tell' has become a hot button political issue in Washington.

Last week, the Defense Department sent out a survey to the troops asking for their opinions on gays in the military.

But one former Pentagon official says asking for troop input sets a dangerous precedent.

Lawrence Korb is a senior fellow at the Center for American Progress. He served as assistant secretary of defense during the first Reagan Administration and has been involved with military issues ever since.

He explains why he thinks polling the troops is a bad idea.
