Not if that particular portion of your state's Constitution is struck by the US Supreme Court. There are plenty of states with Constitutions that define marriage as a contract between one man and one woman, California comes to mind immediately.
But, there's a number of cases working themselves through the federal judiciary that will challenge that state constitutional provision. If the makeup on the Supreme Court ever reaches a point that it finds a ban on gay marriage unconstitutional, polygamy won't be very far behind.
Obama has already appointed one young justice. There's a VERY good chance he'll appoint two more very young justices in the next 24 months (or sooner). If something should happen to Thomas, Scalia, Alito or Roberts, gay marriage in America would quickly become the law of the land, and DOMA would be struck down. That's why it's so important to beat Obama in 2012.

And how, pray tell, could they legitimately strike down a portion of a STATE Constitution when their jurisdiction is a Federal Constitution stating that all the powers NOT expressly delegated to the Federal Government are either the state’s or the people’s power? (See amendments 9 & 10.)
PS — Marriage is not delegated to the federal government in Federal Constitution, therefore it must be either the state’s or the people’s power.
