Why was popular sovereignty so well-supported as a just and fair way to settle the slavery question?

It seemed to have worked well in the Compromise of 1850.
It allowed citizens of a territory to decide the slave issue.
It allowed Congress to have some input into the political events in territories.
It gave people a chance to let the Federal government decide for them.

Popular sovereignty was well supported because it allowed the local
citizens of a territory to decide if slavery was to be allowed or
illegal. Stephen A. Douglas pushed for popular sovereignty during
the 1840's.
