How can states shape public policy?

The state senators and delegates shape public policy by giving bills to the state legislative.

Explanation:

Within the government, there are different administrative bodies, working at different positions of authority, like national, state, and local. They develop their version of policies for their citizens, keeping in mind their own personal interests and values.

In such a situation, the state governments can create policies such that they match the needs and ideas of the people living in that area. These policies should be made by securing a vote of the citizens for the policy living in the region, to make its implementation easier.
