It is clearly evident that Dimitri is no longer fit to rule Rohan. First, he RPs terribly on many occasions, breaks pacts with the DMs, and most importantly, although captured by the enemy, still continues to RP and says that if he comes back he is summoning Morgoth.
I've had enough. The DMs officially declare the Throne of Rohan up for grabs. We will hold another election for Archon once this chaotic war is over. So, if you've ever wanted to rule the second largest country in Middle Earth, you can!
