Lots of people really dislike Donald Trump. Really dislike him. He would be the least popular major-party nominee in recent history, the least popular candidate of any kind since David Duke ran. That doesn't mean that he can't win, of course -- in part because the likely Democratic nominee, Hillary Clinton, is also very unpopular, but less so.

In fact, of the five remaining candidates, only one isn't viewed unfavorably on net by all voters. Net favorability -- the number of people who view a candidate favorably minus those who view them unfavorably -- varies by demographic group, but in Fox News polling out at the end of last month, the candidates were viewed negatively overall in 71 percent of the 90 different combinations of candidate and demographic groups.

You'll notice that we didn't mention which candidate was viewed positively overall above. That's because we've created a little quiz to see if you can guess how popular each candidate is. Anything over zero means that the candidate is viewed more positively than negatively. Anything under zero? More negative.

Okay. Try it out. Then we'll talk more about this beneath the tool.

Here is a GIF of Donald Trump meant to add some space between the tool and the discussion, to prevent you from cheating by reading more about the favorability ratings. It's not that I don't trust you, but, well.

As you may have noticed, it's John Kasich that's generally viewed more positively than his opponents. That's probably in part because he's less well-known; more than 1 in 8 voters had no opinion on the guy.

Which is another thing worth keeping in mind as the general election approaches. If through some miracle Kasich ends up as the nominee, both his campaign and his opponents will try to define who he is and what he's about. That will almost certainly shift his numbers in one way or the other -- but we can guess that they'll shift down, since the more people know the existing candidates, the less they like them.

Bear in mind, too, that this is all voters -- all men, all black voters, all of those making less than $50,000 a year. So there's some overlap between the white vote and the Republican vote, for example, since Republicans tend to be white. Meaning that there's a thread of partisanship that runs all the way through this thing.

None of this is meant to take away from the fact that Trump is uniquely unpopular. He's at another level of dislike. He's the Nickelback of American politics.

It's just that he may end up running against Coldplay.
