I think that graph is a fiction. The people on the other side often feel exactly the same way, that they're voting for the lesser evil. The point about the "lesser of two evils" concept
isn't that one specific side is "evil" and the other is "good", it's that neither side gets their preferred candidate, they vote for the one
they think is the lesser of two evils. That's the entire point. That graph above is a purely partisan mockery of the core concept.
How do you think the far-right felt about Mitt Romney, who implemented health reform in his state as governor? He was a leftie lesser of two evils, and voting for him meant embracing a leftward slide because they had no choice. Those other guys also constantly make the exact same point, that every government reform, project or spending is a step towards communism.
So, you got the far-left saying that voting for anyone at all except the far-left candidate is an inexorable right-wing slide, and you got the far-right saying anyone in power further left than a far-right candidate is just feeding the inexorable slide into communistic government rule.
The graph shown is bullshit basically. If the above image was true, all countries would veer right over time, but they don't.
If you are far-left and you are part of the bunch who didn't go out vote because Clinton wasn't a compelling candidate, then you effectively handed a vote directly to Trump, you didn't stick to some principles about only supporting the left and not letting the country shift to the right. It's the
Trolley Problem basically, where you let the train run over 5 people because then you can say it's not your fault that the train ran anyone over, and it would have hit 3 people on the other track even if you pulled the lever.
Point in case
https://en.wikipedia.org/wiki/Lesser_of_two_evils_principleIn 2012, Huffington Post columnist Sanford Jay Rosen stated that the idea became a common practice for left-leaning voters in the United States due to their overwhelming disapproval of the United States government's support for the Vietnam War.[1] Rosen stated: "Beginning with the 1968 presidential election, I often have heard from liberals that they could not vote for the lesser of two evils. Some said they would not vote; some said they would vote for a third party candidate. That mantra delivered us to Richard Nixon in 1972 until Watergate did him in. And it delivered us to George W. Bush and Dick Cheney in 2000 until they were termed out in 2009".
Yeah, great track record the left-wing abstaining voting is doing. You dodge getting the evil right-leaning Al Gore in power Back in 2000 instead of the Bush Administration. It took
so few votes for that outcome to be a thing. A few lefties in Florida probably thought it didn't matter who won, so didn't turn up to support the Democrats, or they did a pretend vote for a third party with a chuckle: "that'll show 'the man' that we stoners mean business!". End result: Iraq War. Seriously, it's exactly that idiotic attitude as expressed in that graph which causes you to see so many complete Nazi fuck-knuckles getting elected in the first place. Just please vote for the
least Hitler-like person, even if they do kinda suck.
