AGE -- Younger Americans remain more apt than their elders to support gay civil unions and legalizing gay marriages, and to say laws on the issue should be left up to the states. However, they're the least likely age group to call it a make-or-break issue -- 61 percent could vote for a candidate who holds an opposing view.
Seniors, by contrast, are the most opposed of any age group to gay civil unions and marriages, and the most likely to say they'd vote only for a candidate who agrees.
OTHER GROUPS -- All told, support for a constitutional amendment peaks among evangelical white Protestants, conservative Republicans, Republicans overall, conservatives, Southerners and Americans age 55 and over.

Women are more apt to support civil unions than men are, 51 percent versus. 39 percent, and to support legalizing gay marriage, 41 percent versus 31 percent.
