Four years ago I set up a table to keep track of delegates for each of the two major parties. I mistakenly believed that it would be an easy task, but instead soon found that different media outlets disagreed on the numbers.

There are several reasons. The road from vote count to delegates won can be arduous. In the 2012 Iowa Caucus Mitt Romney appeared to be the winner, but the final results showed that Rick Santorum edged him out. Additionally, both parties invite unpledged delegates (oftentimes called “superdelegates”) who may voice a preference but don’t have to cast their vote until the convention.

And so once again I’ve built a table that tracks several media outlets and their delegate count. I only have a few now, but I suspect that as time goes on, more media outlets will have their own trackers.

Interestingly enough, as I write this, all three media outlets show exactly the same numbers. I suspect they are all getting their numbers from the Associated Press.

You can find my tracker here.
