Which kind of groups had more power in the 1700s? Less power? What has changed since then? What hasn't?

The correct answer to this open question is the following.

The kind of groups that had more power in the 1700s were the Federalists and the Antifederalists.

During the Constitutional Convention in the city of Philadelphia, Pennsylvania, these two opposite groups had discussions and debates to decide the new form of government for the United States. Although President Benjamin Franklin did not favor the creation of factions or parties because these could divide the country, since those early years the United States has had political parties that have fought to get to power and rule.

Not so much has changed since those years. Today, a bipartisan system dominates the electoral system in the US, where the Democratic Party and the Republican Party have the monopoly of power in the country.
