Party Of Government?

The designation "Party of Government" applies to those elected (and appointed) individuals who are sucking the money of the taxpayer, usually at the point of the Gummint Gun.

But while the term is accurate and descriptive, I think there can be a minor improvement which will more clearly identify those people and their constituencies:

PARTY IN GOVERNMENT

See, that way, the acronym is P. I. G.

Makes it just a little clearer, eh?
