Hillary would definitely have won Indiana. Remember she had emerged victorious in the open IN primary, and nevertheless Obama got the electoral votes from there.
Thus, Obama's result means Hillary would have been all the more successful in the Hoosier state.
And btw, Oklahoma would have gone much more Democratic than under Obama.
Hillary wouldn't have been able to match Obama's black turnout in Indiana.
I could see Hillary holding McCain under 60% in Oklahoma; still, probably something like 58-42 McCain.
