These emails are no more ridiculous or illegal, than this news story is relevant or interesting.

I don't like Caster. Loathe him in fact, but him telling people to please get out and vote for him hardly seems to constitute illegal activites or anything more than an extremely minor misuse of his county email. These seem like snippets from email correspondences with people he knows rather than him soliciting voters.

Hardly a scandal. Definitely not newsworthy.
Go ahead and dig deeper if there is a story, but presenting this is shoddy journalism.
