Vermont is a winner-take-all state if the winner can crack 50% of the vote. But because it looks like Romney won't hit that number, it'll be divided out proportionally. Romney will take the majority of delegates and Paul will peel off a few. The New York Times' FiveThirtyEight projected that Romney will walk away with eleven of the seventeen delegates at stake.
This will stay developing, but the main headline is in: Romney has won Vermont.
