Seriously? You’re looking at Trump’s favorability in New Hampshire? He won New Hampshire decisively; nobody’s arguing that fact, but New Hampshire represents a grand total of 0.4% of the US population, which is meaningless outside the context of the New Hampshire primary and the general election results within the state.
Over 30 polls going back to May 2015 show Trump’s NATIONAL favorability rating between 18 and 39%, with an average favorable rating of 34.4%. Those same polls show an unfavorable range of 53-69%, with an average of 57.8% - the highest since favorability was first followed in 1992 and higher even than Hillary Clinton. That leaves Trump’s net favorability rating at -23.4%, the lowest of any presidential candidate NATIONALLY.

Whether you like it or not, them’s the facts as they stand today and Trump’s doing nothing to enhance his favorability or likeability.
