New Hampshire Poll: Jeb Bush Grabs Narrow Lead

Jeb Bush has taken a slight lead over other potential Republican presidential candidates in a new Bloomberg Politics/Saint Anselm New Hampshire poll, even though his party’s voters have doubts about his famous last name and his positions on immigration and education.

Even if Bush should overcome those doubts to prevail in what is shaping up as one of the most wide-open Republican primaries in the state's recent history, the poll suggests that he is deeply unpopular with likely general-election voters. It's a worrisome sign for his campaign in a battleground state that both parties have targeted during the past several presidential elections.
