When I was in the 8th grade I tried asking what the difference was. A friend of mine at the time, who was kinda smart albeit the son of a rich dentist, summed it up by saying "Democrats want to give money to the homeless while republicans want to create jobs for the homeless". It made sense at the time and held some truth for a decade or 2.
Whereas now it's "democrats try to get homeless people back on their feet, republicans make being homeless illegal"
