The state Democratic chairman, Joe Turnham, said the party began an investigation last week after hearing about some of Darby's comments in a television interview.
While the party supports the free-speech rights of any candidate, Turnham said some of Darby's views appear to be in "a realm of thought that is unacceptable."
"Any type of hatred toward groups of people, especially for political gain, is completely unacceptable in the Alabama Democratic Party," said Turnham.
It is unclear whether the party could do anything at this point, although the party could decline to certify the results should he win.
