John F Kennedy won the 1960 election by a hair. His opponent was Richard Nixon (who would later be elected). Nixon was a popular sitting Vice President at the time. He felt he would easily win. When he didn’t, he through a tissy-fit and stormed off without asking for a recount, which he was entitled to. Had he, he would have won.
Since that time, and as history gets resolved as time passes, most reputable historians agree that Nixon did win.
I’ll make this as short as I can.
The Kennedy family was very influential but not well known or liked in the mid-west. But, the Kennedys had a mutual friend to the Chicago crime boss, Sam Giancana, Frank Sinatra. Frank was a go-between for the two, and a deal was made for Sam to help JFK get elected president.
The mob put out a “get to vote” campaign that few could refuse. They put out bribes and sent gangsters into the county side. In some counties, JFK was able to get up to 90% of the vote. An impossibly except in socialist, communist countries. After the counting and JFK winning, Sam threw a large victory party there in Chicago. He went around bragging and back-slapping everyone saying, “Hey, we got us a President.” (More will come in my article about the assassination of JFK.)
Democrats have been heavily involved in voter fraud and changing history throughout our, the USA’s, life. More about that in another article. The party can best be described as a cancer.
