I have no idea where you're getting this whole 'couch' thing from, unless it's just another bullshit line fed to you by CNN or MSNBC.
Tell me that Kameltoe Harris did NOT suck her boss's dick when she was working for a congressman - and before you even try, you need to remember that she admitted to it. So good luck with that.
As a prosecutor, she put more blacks in prison for bullshit crimes than any AG in Kalifornia history.
Vance is capable of speaking clearly, concisely, and to the point, while Harris can't form a simple sentence. And there's video evidence of this, so don't even try to say it's not true.
So no, in terms of being capable of doing the job as VP, Harris is a very poor second with Vance being the clear choice - to anyone with an ounce of common sense, that is. So I guess that leaves you out, huh, snowflake?
