You can like from within your feed without visiting their page. I think this is what happens a lot (misclick or deception) within the in-feed ads.

You misunderstand. I never, in the history of ever, clicked Like on any political candidate's page, much less a guy i disagree and dislike.

They're not saying you ever went to a candidates page.

They're saying there was an ad in your own newsfeed you didn't know was an ad. Either a story you liked, or something one of your friends "posted" that you liked, but wasn't really a post, was an ad.
