Today Senator John Cornyn announced that he has hired Brendan Steinhauser as his new Campaign Manager. Steinhauser is a nationally recognized campaign strategist and grassroots organizer whose work helped usher in many new conservative members of Congress in the 2010 and 2012 elections. Previously, Steinhauser was the Director of Campaigns for FreedomWorks, where he ran dozens of statewide issue campaigns, and led the group's effort to elect Ted Cruz to the Senate in 2012. Steinhauser also led grassroots campaigns to help elect Senators Marco Rubio, Mike Lee and Pat Toomey.Still no musings of note that I am aware of, of a possible primary opponent, but he's clearly concerned.
That said, if anybody wants to add to the speculation, please feel free to drop a comment. I've personally wondered if Dan Patrick might switch to hear from the governor's race.
