Warner has a much better shot at pulling in Virgnia than Bayh has at Indiana. Indiana is trending more and more Republican every year.
Republicans account for 46% of Indiana voters against 32% Democrats and 22% Independents.
Assuming those who vote Bayh for Senator vote for him as President, he'll cruise home in Indiana. However, I wouldn't expect 35% of Republicans voting for Bayh as President. It will be lower - but he should still carry his state, if he retains the vast majority of independents
Bayh's always been popular among Hoosiers as governor and senator. I think senators, who have previously been govenors, tend to have a safer tenure
