There is vastly more to an unholy alliance than campaign contributions. The fake opposition of the "opposing" parties usually involves one taking a high moral tone, crusading preachers or government officials who are going "stamp out X" or "regulate Y" or bring a "newer, deeper understanding of Z" if folks will just have faith. It is this last example that relates to Nazi occultism, a sort of hocus-pocus preast-craft to distract the lumpen proletariat from the enormity of Nazi intentions. Likewise, some on the Left stand accused of a double standard w.r.t. Islamist terrorism, again, adopting a high moral tone that masks their acceptance of it. When done to confuse the public, for personal gain, and it works, it's corrupt, politically, i.e., results in policies that do not accomplish their stated purpose, but rather benefit only a few, inside the alliance.
