@H2O MAN,
That is sort of a narrow view of what the USSC decision in Bush actually was about. The selection of electors was being decided from a USSC "primacy decision" in which from an 1891 case said that electors can be chosen from a "geographical area" not necessarily a state.
The Constitution clearly states the process of elections and reafirms the right to vote(State Constitutions also reaffirm the rights of their citizens to include voting) .(Look at all the civil rights and womens suffrage issues contained in the amendments)
