On April 12, Mark Cuban, owner of the Dallas Mavericks basketball team, was interviewed by Chris Wallace. At the very end of the interview Wallace referred to an earlier statement by Cuban that he might possibly run for president as an independent. Wallace said “the deadline has already passed in some states” and said, “You’re aren’t serious, are you?”
Cuban said “You just never know. I’m not gonna say ‘no’. I’m leaving the door open.” Here is a link to the interview. The part about running for president is at the very end.
Wallace is mistaken. Every state has some means for someone running for president outside the major parties to get on the ballot, in the period May through September. Furthermore, the U.S. Supreme Court said in Anderson v Celebrezze in 1983 that it violates the First Amendment for any state to have an early deadline for a candidate to file for the general election as a presidential candidate. John B. Anderson in 1980 didn’t declare as an independent until April 24, but he got on the ballot in every jurisdiction.
In 1924, Robert La Follette didn’t declare as an independent until July 4, and he got on the ballot in every state except Louisiana, and the Louisiana problem had nothing to do with an early deadline. Thanks to Ken Bush for the link.
