The UCP are trying to prolong this whole affair and, I think, trying to pander to separatists without actually risking that Alberta separate.

ETA: There is definitely a significant pro-separatist faction within the UCP, but I don't think the current party leadership is really willing to commit to separating, even if they are buddy-buddy with key figures in the current US regime.

Also note that this referendum does not require that the question be clear (per the Clarity Act), which will allow them to confuse voters and garner apparently higher support, that they can use to coerce the federal government into giving them what they want.
