For those unfamiliar with how American politics has played out over the past several decades, the "Swamp", as described by Trump, formed a Uniparty alliance in which the same goals and desires would be executed by whichever candidate(s) represented their respective party. This was achieved through vote-rigging and manipulation of public opinion, aided greatly by compromised media outlets. It means whether you voted red or blue, your vote never mattered for a second. As I am not an American myself, there may be some inaccuracies. It is impossible to know for sure the depth and breadth of this operation unless you have firsthand experience, but I believe this to be accurate for the most part.
The 1960 election is so far the earliest confirmable election in which this occurred, but JFK would prove too much of a loose cannon and had to be dealt with. From LBJ onwards, it was decided the risks were no longer worth taking and they had to deal with each candidate on a one-to-one basis, to make sure they would not lose influence and further the agenda for their New World Order.
1980: Jimmy Carter proved himself uninterested in the Uniparty's causes and so was summarily dumped in favor of inserting their preferred patsy, George H.W. Bush, as Ronald Reagan's running mate after it became clear public opinion on Bush was too low for him to run against the beloved Reagan. They then attempted to assassinate Reagan early on in his presidency in order to give Bush absolute power but failed, and had to take a back seat for the next 8 years.
1984: An aborted attempt at fraud was committed by the Uniparty in favor of Walter Mondale, but was quickly abandoned, likely following contact with George Bush Sr and the revealing of his intentions for the following election cycle. Reagan slowly ceded power to Bush in the name of good intentions throughout his second tenure, so that by the time 1989 rolled around, nothing significantly changed.
1988: Election wasn't so much as rigged as deliberately engineered against Michael Dukakis. His tank photo was successfully spun by the Bush/Uniparty lobby as a negative thing which took away 25% of his voter base (or is at least claimed to have). Bush's victory was guaranteed no matter how much of a fight Dukakis put up.
1992: Both main candidates, Bush and Clinton, were controlled members of the Uniparty, therefore no voter fraud was required. However, from 1994 onwards, and especially during his second-term, many things were rigged in favor of Clinton to ensure he held his seat through to the new Millennium.
1996: Election was rigged to maintain the incumbent Uniparty candidate, Bill Clinton, against Bob Dole. Dole was one of the few Republicans to throw their support behind Trump in the 2016 elections, although I do not know if this allegiance has since switched. I also believe Dole was the final non-Uniparty main candidate until Trump in 2016, but again, I could be wrong. Following this election, they would focus more on the earlier stages of the election cycle, as they would prove easier to compromise.
2000: Both main candidates, Bush and Gore, were controlled members of the Uniparty, therefore no vote fraud was required. The recount which favored Bush over Gore was a genuine faux pas after much of the Uniparty had already accepted Gore on behalf of the media.
2004: Both main candidates, Bush and Kerry, were controlled members of the Uniparty, although Bush wanted to further America's influence in the Middle East. It is possible some votes were shifted to Bush to help this cause, but at the end of the day, this election didn't matter. Their attention was more geared towards the Primaries and ensuring there were no genuine Democrats that could serve as a threat. This is why Howard Dean's scream was over-publicized in the manner it was, and it proved an amazing help for Kerry.
2008: Obama was unassociated with the Uniparty until he sold out and allowed Biden to serve as his VP. From there on in, votes were shifted deliberately on to Obama in order to ensure his win against John McCain, the Uniparty's insurance policy. Obama not only became Biden's talking head, he initiated himself into the order outright and became one of them. Obama was a popular candidate, but needed the help of the Uniparty to reign supreme.
2012: Both main candidates, Obama and Romney, were controlled members of the Uniparty, although the election was still heavily rigged in order to ensure Obama/Biden retained control. In the (essentially impossible) event Romney won, he would have simply served as a puppet President whilst others called the shots.
2016: Uniparty attempted heavy rigging against Donald Trump, the first non-Uniparty candidate in over 20 years. However, Hillary Clinton proved so deathly unpopular with voters that it was impossible for the deficit to be overcome and so Clinton lost what should have been one of the easiest, unfair elections ever. There was even a brief, albeit abandoned attempt at giving Trump false votes in order to serve as a backup means for Clinton's ascendancy, but the Slab of Beef was too incompetent to have this option wasted on her.
2020: Uniparty executed a rigged election against Donald Trump, and did so by turning their rigging mechanisms up to 11, which wasn't enough due to Biden's sterile popularity. This resulted in co-ordinating the final 5 states in such a blatant manner that they were easily caught, and you now join us in the ensuing war for power between righteous and evil. They fully expected Biden to lose possession of his faculties, whether naturally or artificially-induced, early on in order to allow Kamala Harris to take control of America and turn the United States into the most powerful and influential member state of Agenda 21. This cannot be allowed to occur, else the West as a whole is lost.
Worth noting is that the CIA gained enormous power under Eisenhower, who proceeded JFK. As a WW II general, he resisted sending our boys into foreign wars (somewhat - he still sent troops to Korea) and instead started dark wars and intelligence-run conflicts instead.
