Massachusetts is Massachusetts — it will always elected Republican governors to serve as a defense mechanism against the worst instincts of its overwhelmingly Democratic legislature, especially when they’re as popular and non-controversial as Baker.
There is no way a state as right-wing as Arkansas should’ve been sending a Democrat to the Senate (which is more partisan than the governor’s mansion) in 2010.
What? This is about the governor's races in both states.
Also while you're right about Massachusetts, I wouldn't necessarily bet on it continuing that far into the future, considering the direction the MAGOP is headed in.
