Do you have a favorable or unfavorable opinion of Bill Nelson? Favorable 49% Unfavorable 11%
Those are quite good ratings. A little weak on the favorable side, but excellent on the unfavorable side.
Harris is obviously a non-starter as a candidate, 40 points down, she's a joke, but if McBride were to somehow pull off the upset he would have a chance to make the case that Nelson has been too quiet/ineffective.
Either your copy/paste function is impaired, or you are deliberately attempting to mislead by omitting the 40% undecided in the Nelson survey response.
