No law, varying the compensation for the services of the Senators and ERepresentaties, shall take effect until an election of Representatives shall have intervened.
You’re exactly right. This way they don’t have to vote on it every year or have it on their conscience. It’s sort of one of their stealth perks. However, they aren’t stepping forward to overturn it. Inevitably, some lonely congress critter finds the fortitude to sponsor a bill every year to strike the automatic part of their salary increases. Few, if any, sign on to support it.
Snakes in the grass. I’m sick of the lack of integrity on the hill.
