Obviously we can't contact Carter of Obama directly. I presume that you can therefore point me to their writings which claim Psalm 22 is about Jesus.Either her or Jimmy Carter and Barack Obama.
Or have you made the mistake of presuming that everyone who claims to be a Christian really believes and those that do believe; believe the same bits of the story and take the same understanding as yourself.
Christianity if a hopelessly split faith. There are over 34,000 separate denominations. Even within a single denomination followers can not agree what is right or what the bible means.
It is very unlikely that Jimmy Carter or Barack Obama share your view of God. Not that their belief, or lack of, in any particular God sway me one bit.
