What relief could the Supreme Court grant? The Constitution does not provide for a new election. Do you want an activist court to take over the selection and qualification process? The Supreme Court is not going to get involved in this case, as I opined above. The Congress is empowered by the 12th Amendment to make the final decision. Any concerns should be addressed in a petition to the next Congress not to the courts.
1) Rule that electors can not vote for Obama
2) Rule that any results from the current college are tainted by the fraud and that new electors must be appointed
3) Rule that Obama can't be President and that Congress must follow the letter of the 12th. Since they have to vote only for the candidates that received electoral votes, only McCain would be the remaining option (however, Biden would be the VP)
4) Rule that the current electors remain but can't vote for Obama but can vote for any candidate (Hillary option)
5) Rule that the votes that were to go for Obama now go to Biden who becomes the President and then appoints his desired VP
... and I'm sure that there are other options out as well
