I'm still trying to figure out what the "bombshell" is here?
Even if the emails are real and that Joe met with one of Hunter's business associates, what exactly is the illegal activity on Joe's part? At best, you've caught Joe in a lie when he said that he didn't know much about Hunter's business (and even that is a stretch, I've met some of my son's school friends, but that doesn't mean that I know what they talk about in the lunch room every day).
I mean, I understand the allegation that Burisma paid Hunter millions to gain influence with Joe, but what are the official acts that Joe Biden did as vice-president that helped Burisma?
If this was a Quid Pro Quo, what was the Quo?
Don't we have records of every foreign policy decision, every tax grant, every memo and correspondence that Joe Biden and the Obama administration made in regards to the country of Ukraine? Wouldn't you think that the DOJ / FBI under Trump's watch would have been digging through those records to find the way in which Joe Biden repaid Burisma for all of the kindness they showed his son? It's been over a year and a half since Trump started trying to find some connection between Burisma and the Bidens. It's not like Joe can just make a call and suddenly the United States grants 50 million dollar contracts to Burisma and there is no record of it. The US government is not the most morally straight organization on the planet, but if there is money changing hands, you bet your sweet bippy that someone has a receipt.
If your argument is the "He got Shokin fired. That's how it helped Burisma" angle, that's not going to fly. Everybody wanted this guy fired (European union, Obama Administration, even some Republicans signed off on it). And regardless of Joe bragging about it, Shokin was not immediately fired because of Joe's threat. It was months later, by unanimous vote in the Ukraine parliament.
So somebody give me the "Quo". Till then, this is just crap being thrown at the wall to see if it riles up the base and gets 1 in 100 independents to change their vote without any evidence of a law being broken.
