In the north, the dred scott decision was: popular unpopular of no effect at all

The correct answer is unpopular.

The Dred Scott decision was a Supreme Court case that ruled that slaves are considered property, not people. Along with this, the Supreme Court ruled that slaves had no legal rights that white citizens are bound to respect. With this in mind, the ruling official allowed slave owners to bring their slaves anywhere in the US, even the states that already outlawed slavery in their constitution.

This was widely unpopular in the North, as slavery (in theory) could now ecist in their state.

americans had many intangible advantages. well since the british fought a war far from home military orders, troops, and supplies sometimes took months to reach their destinations, and the british had an extremely difficult objective. they had to persuade the americans to give up their claims of independence, americans had a grand cause: fighting for their rights, their independence and their liberty. this cause is much more just than waging a war to deny independence.
