(I think the we is good - you look on it as an observer and then draw the audience in to make a wider point so don't scrap that please)#

I really like this, I don't know if you had intended this but a friend of mine said at the last election that really it was a campaign of the 'lesser of two evils' obviously, she was a Democrat but sometimes...neither choice is fair

I like this and how it tells a tale of all humanity from these two kings. Just throughout the poem, you are in the third person writing of the kings, then the last line you switch to "we'll." Perhaps adjust that. It sounds a bit awkward. Another suggestion: your use of punctuation is a bit sporadic and not as thought out as it could be for a good poem like this. There are places where the reader wants to pause, etc. So just look it over adding comas and periods... Otherwise it is very powerful.
