In a personalist regime, the power is held by a single leader, whose demands become law for the entire country.
This regime is a form of autocracy. It is a government system that operates as an absolute monarchy or a despotate. Personalist leaders are able to appoint friends or family to important offices. As a consequence, population gain respect for their leader. For example, the Kim dynasty in North Korea.
Ronald Reagan (1980-1988) was a conservative Republican. His ideas couched in democratic ideology and republican values appeal to and were popular with many Americans.
You don't specify the time period so I'm going to assume you mean after 2008. The government lowered interest rates and increased infrastructure spending.
