Walker's dullness may prove an asset, no?

[Mister Mets]

I don't think it'll be a major issue given the competition.

That said, problems with the performative aspects could accentuate other shortcomings. A dull professorial type could be competent. A charistmatic guy could obscure intellectual shortcomings (see W.) Someone who isn't too bright and isn't very exciting is a lunkhead.
