CNN returns here 

CNN exit polls here

Polls have closed and it looks like Senator Clinton is the winner of the Puerto Rico primary. It is of course something of an empty victory since the nomination is all but wrapped up for Obama.

Returns are starting to come in so it will be a while before we know for sure the exact results. CNN, Fox and MSNBC have all called it for her. Word seems to be it will be a fairly large win though with low turnout it may not help her much in the popular vote battle, in fact he may balance it out on Tuesday in Montana and South Dakota.

Based on CNN exit polls, she looks to get around 70% of the vote, but that would shift only about 20-25 delegates her way, which is not enough to prevent Obama from going over the top in the next week or two.
