I haven't followed closely the saga of Joe Biden's alleged family conflicts in Ukraine and China when he was Vice President, but I'm aware that claims and counterclaims have been percolating through the mainstream and non-mainstream media and in the Democrat primary field.
Being in the position of just hearing about it and seeing reactions, I'm a typical news consumer. And what I'm sensing, and have sensed for some time, is that Ukraine may be to Biden's campaign what emails were to Hillary's campaign. And China could get there too.
