South Carolina deserves Haley in any other state this race would be Likely D with all of Haley's baggage.
Not true. There are GOP governors with more baggage that are likely to be reelected again in democratic-leaning states: Walker, Snyder, Kasich, Scott (not that likely, let's see how FL develops).
OH and FL aren't D-leaning states and even WI would probably only be a tilt D state. Also, out of those four Governors mentioned, 3 are likely to fall to defeat (Snyder, Kasich and Scott - Walker's race will be razor-thin though).
As for the topic at hand, Haley might have more money than that if she didn't waste it all on vacations and "voter fraud" from dead people. From that, it looks like Sheheen is competing pretty well financially , but it's still lean R and a race where Haley needs to do something awful again to give Sheheen a shot. If she endorses Sanford for re-election, that might not blow over well with South Carolinans.
