One of the most effective ways for liberals to infiltrate into red districts is to become RINOs. They are blue inside but act like republicans to get elected (and re-elected) and at the most effective time turn to their liberal core. These aren't republicans. These are democrat wolves in elephants clothing. This is just one more deceitful trick the democrats use to destroy the balance of power. They serve only their own interests and the interests of those who enrich them with wealth and power. These are the demons who prey upon gullible boomers and normies who can't see through the charade. Don't call them republicans. Call them liars in disguise.

I wonder how their constituents might express their disapproval for the actions of the individuals who were elected to represent them in Congress.

I’m sure there are many ways to do so.
