The correct answer to this open question is the following.

Although there are no options attached or further context and references, we can say the following.

Individuals or politicians should act in the following way in order to protect our democratic institutions.

Citizens have to actively participate in politics. It is their right and obligation at the same time. To participate in elections is the democratic way to elect their representatives in Congress. That is how the Constitution stated the way in which the people have the liberty to elect or dismiss their representatives.

Once they are elected, citizens must follow closely the work of legislators. Congressmen are in their offices to serve the people, their interests, and their concerns. Legislators are not elected to serve particular agendas or interest groups that hire a lobbyist to negotiate laws that can benefit them.
