My guess would be that amongst the match attending fans the vote would be well in Bob’s favour.
Not sure I agree with you there. There’s a difference between supporting someone because he’s the manager of your club, as we all do, and actually wanting him there and enjoying his football.
My guess is that those in the latter camp are 50:50 of total matchday support at best. If you add in all the other more casual fans who have clearly been driven away by his negative, dull and predictable football (look at the gates this season), there would be a majority against.
Put another way, if you were offered Martinez or Hodgson as manager of our club through to the end of this season and beyond, who would you take?
