It's just if what the caller says is true, and anyone who has had the Sacrament of Confirmation has the God-given authority, then The Church has the potential to swiftly raise an army of real spiritual warriors against the demonic forces so manifestly in charge of so many of our leaders.
Could there be so few as 50 righteous people within the lay Catholics to go 50:1 on a demon influencing a single politician?
Or would you cast your Lot that we passively go the way of Sodom?
I took some training with an interfaith charismatic group who were deep into spiritual warfare. They prayed over people and worked with doctors and the clergy to deliver those oppressed or possessed.
But there is a difference between spiritual warfare, which is the privilege of all Christians, and exorcism, which is “mano a mano” fight with a demon, who could turn around and affect you or your family.
Also, unless one is mentally stable and spiritually solid, you could end up being affected by the demon.
