Lets say that in 1901, President Mckinley was not Assassinated, and that he lived to serve the rest of his term. In 1904, were would that leave his vice-president, Thedore Roosevelt, who in the OTL would be running for president. Would he still be the nominee for the republicans? he was never very popular among them? And if not him, then who would go on to be president? and whow would this affect the rest of american history?
