conflating what sounds -- sounds like two or three remembrances at the same time just because donald trump doesn't tell the truth all of the time doesn't mean that that isn't potentially a problem for joe biden as it relates to authenticity or providing, to cara's point, a clear choice. they are not equal. it doesn't mean one doesn't matter. >> the gaffes aside, it is pretty remarkable how despite all of the arrows that joe biden has taken since he entered the race in april, how resilient he has. so he makes verbal errors and conflates details of stories and he's taken hits from the other candidates and flip-flopped on the hyde amendment and attacked on trade and the busing issue and the crime bill and yet he still remains at the top of the polls so the ability to beat trump seems to be at the front and foremost of voters' minds at this point. >> thanks everybody.
