I don't get what this is?

I read the first one. Some DNC person asked another "Finance asked us to vet as potential POTUS host/donor." The vetting came back that he had a record:

George Lindemann - convicted of three counts of wire fraud in 1995 and received a 33-month term in federal prison; Investigation stemmed from a federal investigation where over 50 horses were killed in a 20 year period in acts of insurance fraud; nothing new as of 5/9/16

Then the reply is "I vote fail....again."

That sounds like they are saying not to invite him?

I dunno..

The "Re: BuzzFeed and DNC connection." one is an introduction email. To quote:

Adrian, thanks so much for the intro! Hi Luis, great to meet you. We are currently putting together some plans around the conventions and some other cool stuff, would be nice to connect down the line.

I completely concede I didn't read all those links, but it kinda looks like someone just glanced at some subject lines and pasted the links.

I'm really having trouble seeing what is supposed to be such a big deal.

Yes, nothing is a big deal. Just corruption as usual...

Please don't do this here. HN threads are supposed to be conversations.

Maybe spread it somewhere else.

Yes, how inappropriate to post it in a thread about the DNC email leaks !

Copypasta's are not usually appreciated on this website, in my experience.

If I had stripped the attribution no-one would have been the wiser
