Right now Republican voters believe that Trump is (a) the most likely to shake up our nation’s capital and (b) has the best shot of winning in November.Some 43% of Republicans believe Trump is the most electable of their candidates for nomination. This is particularly striking when you understand that the same poll found only 32% actually prefer him. Thus, roughly one Republican in ten thinks Trump is more electable than the candidate they personally prefer.
A political campaign is truly a marketing campaign, where the candidate is the "product" being promoted. Trump's marketing savvy is known to be formidable; obviously voters don't underestimate the potency of his sales skills, as many pundits have.
