I know that by "dear leader" you mean to imply that Trump did something unfair/wrong/sinister/etc ("just like Hitler", amirite fellas?)., but a leader of a large group of people, by definition, is good at persuasion.
Franklin Roosevelt moved the Democratic Party in a direction very different from its first century. The party's two previous presidential nominees were a Wall Street corporate lawyer (John W. Davis) and Al Smith who, despite also being a New York City resident and state governor, so opposed FDR by the end of his first term that he founded an influential anti-New Deal organization. During the Roosevelt years the Democrats lost significant support from traditional backers, but more than made up for it with gains elsewhere in what became the New Deal coalition.
Similarly, under Trump the GOP lost support in wealthy suburbs but gained support elsewhere, such as Rust Belt states, Latinos (including places like South Florida and the Texas border region), blacks, and (according to current polls) young voters. We'll see whether one compensates for the other.
