Directly behind those two was frontrunner Donald Trump, whose added 10,000 followers to his already massive total of 4.16 million. Florida Sen. Marco Rubio and former Florida Gov. Jeb Bush each gained 7,000.

At the back of the pack were Ohio Gov. John Kasich, Kentucky Sen. Rand Paul and Texas Sen. Ted Cruz, who added 3,000 followers a piece.
