Same As It Ever Was 

by tristero

Horribly, it is quite plausible that a major-party presidential candidate would willingly collude, and possibly sponsor, a foreign government to create mischief in order to influence the election in his favor. Nixon did it:
It begins in the summer of 1968. Nixon feared a breakthrough at the Paris Peace talks designed to find a negotiated settlement to the Vietnam war, and he knew this would derail his campaign. 
He therefore set up a clandestine back-channel involving Anna Chennault, a senior campaign adviser. 
At a July meeting in Nixon's New York apartment, the South Vietnamese ambassador was told Chennault represented Nixon and spoke for the campaign. If any message needed to be passed to the South Vietnamese president, Nguyen Van Thieu, it would come via Chennault. 
In late October 1968 there were major concessions from Hanoi which promised to allow meaningful talks to get underway in Paris - concessions that would justify Johnson calling for a complete bombing halt of North Vietnam. This was exactly what Nixon feared. 
Chennault was despatched to the South Vietnamese embassy with a clear message: the South Vietnamese government should withdraw from the talks, refuse to deal with Johnson, and if Nixon was elected, they would get a much better deal. 
So on the eve of his planned announcement of a halt to the bombing, Johnson learned the South Vietnamese were pulling out. 
He was also told why. The FBI had bugged the ambassador's phone and a transcripts of Anna Chennault's calls were sent to the White House. In one conversation she tells the ambassador to "just hang on through election". 
Johnson was told by Defence Secretary Clifford that the interference was illegal and threatened the chance for peace. 
Nixon went on to become president and eventually signed a Vietnam peace deal in 1973
In a series of remarkable White House recordings we can hear Johnson's reaction to the news. 
In one call to Senator Richard Russell he says: "We have found that our friend, the Republican nominee, our California friend, has been playing on the outskirts with our enemies and our friends both, he has been doing it through rather subterranean sources. Mrs Chennault is warning the South Vietnamese not to get pulled into this Johnson move." 
He orders the Nixon campaign to be placed under FBI surveillance and demands to know if Nixon is personally involved. 
When he became convinced it was being orchestrated by the Republican candidate, the president called Senator Everett Dirksen, the Republican leader in the Senate to get a message to Nixon. 
The president knew what was going on, Nixon should back off and the subterfuge amounted to treason. 
Publicly Nixon was suggesting he had no idea why the South Vietnamese withdrew from the talks. He even offered to travel to Saigon to get them back to the negotiating table.
Johnson felt it was the ultimate expression of political hypocrisy but in calls recorded with Clifford they express the fear that going public would require revealing the FBI were bugging the ambassador's phone and the National Security Agency (NSA) was intercepting his communications with Saigon. 
So they decided to say nothing. 
The president did let Humphrey know and gave him enough information to sink his opponent. But by then, a few days from the election, Humphrey had been told he had closed the gap with Nixon and would win the presidency. So Humphrey decided it would be too disruptive to the country to accuse the Republicans of treason, if the Democrats were going to win anyway. 
Nixon ended his campaign by suggesting the administration war policy was in shambles. They couldn't even get the South Vietnamese to the negotiating table. 
He won by less than 1% of the popular vote.
Adding: the notion that Trump is in any way anomalous is belied by this story. There has been something very sick and dangerous afoot in Republican party post-Eisenhower, and especially post-Ford. Trump is only the latest manifestation.
