Lots of downticket races can be swung by a popular presidential nominee.
That said, Oklahoma’s awash in O&G money and its state bureaucrats are notoriously corrupt. At some point, the sheer volume of gerrymandering, vote caging, and criminal disenfranchisement needs to be addressed. Simply shouting at people to “GO VOTE!” when they’re getting handed broken machines and defective butterfly ballots and threatening robocalls isn’t helping anyone, least of all the candidates they’re hoping will win.
