Sounds to me like @Caroljo needs to look up "REPUBLIC".sounds to me like @MV needs to read the words to the Pledge of Allegiance!
"I pledge allegiance to the United States of America, and to the REPUBLIC for which it stands"
We do not vote on legislation...our representatives do. Whether or not we have the electoral college (where electors are picked by rules devised by individual states) or by a popular vote would not change us from a republic.
republic:
a state in which supreme power is held by the people and their elected representatives, and which has an elected or nominated president rather than a monarch.
What form of government is the United States?
The United States government is best categorized as a constitutional federal republic. This means that the United States is governed primarily by elected representatives and an elected leader, and that power is balanced between the federal government and the governments of the states.
