The cache IS at the posted coordinates but don't misunderestimate this challenge. In order to log this, you must add up the electoral votes of all U.S. states in which you have found a cache (in accordance with the 2016 election) and they must total at least 270. All it takes is one cache in a state in order to count that state's electoral votes but there is no way around it -- this requires a lot of travelling (hence the difficulty level).

As far as requiring you to post proof that you meet the challenge requirements, I'm not gonna do it. I will check the statistics on your profile, though, and logs will be deleted if the challenge is not met.
To those who don't currently meet the challenge requirements, I feel your pain...but also envy you, as you now have a great excuse to tour this great nation (as though you needed one) and make geocaching great again!
