A mad scientist was murdered and his invention was stolen, it is a disposable time machine which can instantaneously allow any person to swap minds flawlessly and painlessly with anybody from the past. How can the user used such device to become a president? There are countless of timelines spontaneously being created and one of them must be where the user becoming the world leader, the targeted person must not be already or going to be a president himself or participate in any presidential elections. After the swapping both parties will have no recollection of each other memories.

Travel in time and swap minds?
But if your question is "when and where would be ideal opportunity to do such thing" then you have two options:
- choose time in target life when his personality change would not be noticed or explained by some external stimuli (maybe war, military training, long vacation in Himalayan)
- you have time machine so acting in linear manner don't apply to you. You can travel in time to any period, change/influence targets life, jump to another time do the same to somebody else, jump back to first target 10 years later, change/influence his life again and so on and so on.
The second one is more efficient if you have a greater scheme in mind (like, I don't know, starting turmoil in middle east in 1980's to start World War III 40 years later) and less time consuming. You need few days of your life to alter somebody else life instead of sacrificing few years to fully impersonate candidate.
I'm going to do this the hard way.
Pick a person you want to be president, anyone as long as they're eligible, it doesn't matter. Pick yourself if you like.
Standing for one of the big parties saves time later, but you can go independent, it'll just take longer. If you pick a worthwhile candidate to start with it'll be an easier ride once you're into the system.
Now spend the rest of your life swapping bodies with voters to elect your candidate. There's no point being subtle, just work your way down the opposition voting lists first, then start on the unaligned. At some point you'll have done enough to elect your president.
