I'll be updating those numbers over the weekend by the way. What I have been doing is tracking new followers added for each candidate since August 1 to see where the momentum is. Besides Trump, Ben Carson and Carly Fiorina have had the most Twitter momentum (as of last Sunday). A search on "Twitter Standings" as a subject title will pull those threads up.
I'll reset everything the first of each month so that the data does not get stale.
