Since the LA race will be heading to a runoff, a lot depends on how Senate composition looks on Wednesday morning. It's a strong possibility that Louisiana is the 51st seat for Republicans (a 50-49 Republican edge being the case after Election Day, assuming no other runoffs) which, if that is the case, Landrieu will lose something like 45-55 in the runoff.
I hope she and Pryor do "pull a Thad Cochran" and somehow win their races, but it's a lot easier for moderate Republicans to build last minute Black support than it would be for moderate Democrats to create a last minute coalition including conservative Whites in 2014. Nevertheless, I like the campaign Mary is running and I'm hoping we can somehow send her and Pryor back to the senate while still having a GOP majority.
If it goes to a runoff which determines control of the senate, the race moves to
Likely Republican. I agree with you, in a perfect world Republicans take control of the senate while Landrieu and Pryor keep their seats.
