Mavericks' Mark Cuban wonders about Iowa crossover voters as report suggests Haley could see bump from Dems

Former South Carolina Governor and U.N. Ambassador Nikki Haley calls out former President Donald Trump ahead of the 2024 Iowa caucuses. 

Dallas Mavericks minority owner Mark Cuban wondered whether any Democrat voters were going to cross over during the Iowa caucuses amid a report it could be a boost for Republican presidential nominee Nikki Haley.

Cuban posted a link to an Axios story that suggested Democrats "could give Haley a boost in Iowa caucuses." The report said some Dems and independents in Iowa are "planning to crash" the Republican caucuses Monday night and vote for Haley in hopes of being a roadblock for Donald Trump.

"Any Iowa crossover voters out there?" Cuban wrote on X.

Iowa allows day-of party registration for prospective voters. Axios called it one of the "low-key" traditions in the Iowa caucuses. One of Haley’s precinct captains in Cedar Rapids, Iowa, told the outlet the candidate may receive some "good crossover" as Dems get to essentially choose who they want President Biden to oppose come November.
