“A bakery in Louisiana refused to bake a birthday cake featuring the words “Trump 2016,” prompting questions as to whether the business will be fined in a similar vein to how Sweet Cakes by Melissa, a cake shop in Oregon, was forced to shut down after its owners refused to bake a cake for a gay wedding.”
My guess is no, as Oregon laws do not apply in Louisiana.
Even in Oregon political affiliation is not a protected class.
