There are many advantages of living under a constitutional government.
But first, know that the government in 3rd world countries can be as good as the government here as it is there. One major advantage to list is that the U.S.A is a very free, and fruitful country to live in, we are one of the hardest countries to get into because of our laws, language and many other disadvantages. We also have a government who listens to our complaints and have a budget to have action behind words.
A party organization that recruits members by dispensing parronage.
I'm pretty sure that would be to remove Union pressure from Virginia. Virginia was being destroyed by the Civil War and Lee, who was only fighting for the Confederacy because of his home state, which was Virginia. Because of this, he invaded Union territory to move the fighting to Union territory to protect Virginia. Hope this helps!
