Twelve Republican presidential candidates and seven Democratic presidential candidates filed for the Oklahoma presidential primaries. This is the largest number of Republicans in an Oklahoma presidential primary in history; the previous high for Republicans was eleven in 1988.

Here is the list of candidates from the Oklahoma State Board of Elections webpage. If one scrolls down, one can see copies of each candidate’s filing, which includes the candidate’s home address and date of birth, details which seem somewhat invasive of the candidates’ privacy. Also one can see each candidate’s signature. Donald Trump’s signature is interesting.
