For every candidate save two in the Democratic and Republican presidential contests, what goes up must come down. Some of the downturns we've seen this year -- perhaps even among eventual winners -- have been stunning.

We graphed seven drops in the polls experienced by 2016 candidates so far. In each case, the yellow line shows the change between their highest point in the Real Clear Politics polling average and now. If they peaked at 27 and are now at 7 points, for example, the far left end of the line will be at +20, because they lost 20 points.

We will warn you in advanced: This ain't easy. But if you're the type who likes to try to prove his or her political chops (*cough* chris cillizza *cough*), this is your chance.
