But can we read anything into these numbers?
Following their entries into the race all four contenders set up dedicated campaign Twitter accounts and the numbers in the chart above show how many followers they have attracted.
All of these were created at about the same time so comparisons are valid. The question is what can we read into the numbers?
What I find interesting is that the contenders perceived as being the most left and right wing are the ones that have done better. What this might indicate is that their support base base in more enthusiastic. Certainly the Tweeting by their campaign and by Corbyn and Kendall themselves has appeared to be the most effective. They are using the medium well. Cooper and Burnham, meanwhile, appear to be a lot less sure-footed in their messaging.
There’s a long way to go. Ballot pack start going out in more than five weeks.
