According to the Texas Tribune, Ted Cruz showed up at the Kim Davis Freedom Rally and was shown the door by Mike Huckabee’s handlers. According to Patrick Svitek with the Tribune:
In the footage, Cruz exits the Carter County Detention Center, where Davis was being held, and heads toward the microphones where Huckabee was later broadcast alongside the clerk. However, Cruz quickly runs into a Huckabee staffer who points him in another direction, setting off a roughly 15-second back-and-forth followed by Cruz repeatedly trying to maneuver around the staffer. Cruz, appearing dumbfounded by the situation, ultimately follows the staffer offscreen.
A cynical person might take this as evidence that the Kim Davis controversy isn’t about same-sex marriage but capturing the religious right vote.
I don’t know for sure, but I heard that Cruz and Huckabee broke out into song and dance after the presser and sang this together.
