“The leftists hate Columbus. they fail to realize that the New World would still have been found a few years later by Pedro Ãlvares Cabral.”
It had already been found 492 years earlier, by Lief Eriksson.

Actually anther may have been first, a fellow named Bjarni Herjolfsson but that would have been a near impossible name for a country or a place.
What if Columbus had returned to Spain and told no one about what he found, the route to India blocked. Then Cabral later finds Brazil and reports to Portugal about his find, unleashing a wave of exploration of the New World.
Could Columbus then say....ME TOO! ME TOO! and have a real claim on discovery?
