The staff will typically keep a record of who called (often verifying the address to make sure they are constituents), what they are calling about, and for/against.

This is also done with faxes, emails, and on the web form.

If it is something that gets lots of people calling in, as in far higher than normal, the representative may choose to view it as a reason to vote a certain way. They are, unfortunately, not obligated to do so. This tactic is especially effective during election years as they may see it affecting their reelection.

Idaho is currently trying to do exactly that....

It's to normalize a lack of choice for the population. Next it will be clothing choices or vaccines or crossing state lines.

It is also to counter the declining population in the worst way possible.

And finally, it's to keep people poor helping to create a permanent underclass. Preferably one that will view military service as a step up.

It is about the cruelty at this point. They can say that all this happened under Biden and bam, their voters believe it.

Or they can blame the results on those that were not given the option to choose by framing them as immoral.

Everyone with more than 2 brain cells to rub together could see this outcome. It will unfortunately be replicated in other states.

Tennessee has screwed themselves for the next 20+ years in 9 months just because they want to control the choices of the population.
