The AFSCME (lobbying organization for public employees) is in the top 5 for campaign contributors since 1990 and supports Democrats almost exclusively. Lots of republicans who aren't hardline ideologues oppose expending the influence of public employees' unions.

Given that the GOP constantly disparages and insults them and their members, I can completely see why they wouldn't want to support GOP candidates.
