This is a Pro-Reagan video from the 2008 national Republic convention. It is a classic style of video for American politicians. It does its best to play up the American dream "Rag's to riches" angle, speaking of his modest family background and his "hard-drinking" father. They also play up Regan's famous humour, even comparing him to Abraham Lincoln, which shows how high they think of Regan as Lincoln is possibly the most respected of all America's presidents.
According to the video Regan brought about great changes in America's economy, lowering inflation and creating jobs. The end of the video even goes as far as to describe him as having saved America, saved the century, and while it stops short of saying he saved the world, it does argue he changed it.
Any American political videos have to be taken with a pinch of salt as they are effectively just advertising a person, making them strongly biased, yet ones made with the added bias of nostalgia like this are exceptionally heaving with hagiography.
