Popular conservative blogger Ed Morrissey of HotAir explains his vote:

"...Before I left Minnesota to spend the election in California, I cast my ballot in support of both measures, and I’ll explain why — and urge my fellow Minnesotans to join me.

First, contrary to what the measure’s opponents have written, it doesn’t change the definition of marriage in the state.  Marriage in Minnesota is restricted by statute to one man and one woman.  The measure would amend the state constitution to define it more foundationally.  That puts the issue outside the reach of the judiciary, which in other states changed the definition of marriage without voters having any say in this government policy.  If at some point in the future Minnesota voters want to change the definition of marriage to something else, they can amend the state constitution to do so — and only need a simple majority of all ballots cast, as is the case today.  Citizens who believe that representative government and direct democracy are better forms of self-government than judicial fiat should support this process."
