Somone should ask Kasich if he actually met with Biden , had an in depth conversation , found Biden to be engaging and knowledgable and what common political ground they have found. Very much doubt that Kasich has even met with Biden or how Biden has devolved politically or mentally matters to him. He is acting on Trump hatred.
Do you think Kasich would answer honestly if he had spoken with Biden? He hates Trump enough that he would lie about Biden, just like he will do with whatever speech he gives at the convention.
