The issue, of course, is not just the vulnerabilities of Hunter Biden.
It is the fact that the Bidens were running a variation on the Clinton’s pay to play influence peddling and extortion scam, and Hunter was the bagman.
Obama certainly knew about _that_, and certainly knew that the cokehead Hunter was a key player, and certainly knew that the Trump campaign would know about it....so Obama would have known a Biden campaign would be a risky bet.
“Send Hunter to do this! Send Hunter to do that! Send Hunter to pick somebody up at the airport. Did you ever think about how I felt? I was stepped over! I’m smart! Not dumb, not like everyone says, I’m smart!”
Probably why obama said “You don’t have to do this Joe”
