No, they cannot, at least not political speech...the "sit-ins" at restaurants across the South decided that issue back in the 1960's. That was political "speech" on private property.

To add to my prior response, in most states with Concealed Carry Permits, you can be charged with trespassing (or worse) for carrying your firearm onto their premises if the business says that your firearms are not allowed or wanted on their premises. That would also be considered political speech, would it not?
