Honestly, I thought they both came off as stubborn idiots.
I think I said that. Two Yorkshire alpha males...
Though, to be fair, Jeremy has the advantage in that his idiot is essentially an onscreen character played by a bloke with the same name, whereas Prescott doesn't have that layer of protection in the first half of the segment (he seems to develop it and settle on a character from the "connect with the electorate" line onwards)
Clarkson's statements about executing striker workers indicates his stupidity might go deeper than his on screen persona.
