As Republicans take stock of the ever-morphing 2020 Democratic field, many are raising the alarm about potential contender Beto O’Rourke who they see as wielding significant fundraising abilities and a chance to win Texas, where President Donald Trump has recently lost popularity.

According to a Sunday Politico report, the Club for Growth has prepared an ad spot to highlight O’Rourke’s “white male privilege,” an attempt to distance him from former President Barack Obama, to whom he’s often compared.

“We watched what he did in Texas in the race against Cruz and realized his potential within the Democratic primary system is enormously larger than what people are giving him credit for right now,” Club for Growth president David McIntosh told Politico. “We realized, here is a real potential threat because if he is the nominee then Texas suddenly is in play.”

Sen. John Cornyn (R-TX) is also reportedly working with Republican groups to ramp up on the ground operations in his home state to counter O’Rourke’s popularity should he enter the race.
