I had to Google it because I’m not from the area but Bexar County seems to be in Texas.
Bexar County = San Antonio basically. Pronounced “bear” like the big furry animal.
Sorry I left out references to San Antonio. I was posting from my phone. The San Antonio Express-News makes it difficult to cut and paste text.
it’s all good! Thanks for the additional info, including pronunciation. 
But isn’t it probably too late for the courts to do anything in time about it?
There’s nothing that courts need to do. Daniel J. Sullivan and Daniel S. Sullivan are both legitimate candidates that should stay on the ballot.
Trump(DOJ) has filed suit, that’s where the courts get involved. They need to rule that the states run their elections, not Trump, and quickly and emphatically.
