Well now that you mentioned it, the NLR are still accusing us of being evil and continue to call Celestia a Tyrant, basically, they are still making lies and think they are the good guys when they are not.
Well in any kind of election that draws the positional power of the type of government held over a country (Solar Empire-Monarchy, NLR-Democracy) it has a higher chance of open rebellion to determine the one in power(Celestia or Luna).
Being how the Solar Empire won I suspect that all it takes is the will of a single pony (lol Modern Warfare reference)to make it happen.
As Supreme Commander 2 quoted "A civil war will break the bond of 3 friends"...or in this case 6
I have to correct you on this, but The NLR are not democrats, they are republicans as you can see in their name. The Solar Empire haves more than one type of government, including the NLR. The Empire's type of government is a mixture of Monarchy, Democracy and maybe a type of Dictatorship (since they sort of remind me of the Roman Empire). The NLR's type of government is a mixture of both a Monarchy and of course, a Republic.
