Oes Negative Attack Campaigns have an impact on US Presidential Elections?

See paper outline attatched. If possible could you send it to me in parts like how it deems we should turn them in since I was addded into the class very last min and need now to catch up since moving to a new school. I am behind and have a full load of AP Class on top of sports! Luckily my teachers are being very AWESOME and giveing me a couple of weeks to catch

I would like to incoorporate Youtube Videoes of Presidential Ads for disscusion in the paper. Also I would like the the intro to almost read as a story and sorta convey my overarching question as a way to explain its importance. Thank you!
