Bernie Sanders has now won seven of the past eight state contests.

Bernie Sanders is still behind when it comes to delegates, but he has one clear advantage over his Democratic and Republican presidential rivals - a lot of people actually like him.By 48 per cent to 39 per cent, more Americans have a favorable than an unfavorable opinion of the Democratic candidate, giving him the best net-positive rating in the field, according to a new Associated Press-GfK poll.Unlike the other candidates, Sanders also is doing better as more Americans get to know him: His favorable rating is up from an earlier AP-GfK poll.The numbers speak to Sanders' rapid rise from a relatively unknown Vermont senator to a celebrated voice proclaiming political revolution.They also reflect how unpopular the rest of the field is.But the growing popularity may be coming too late for Sanders, who lags Democratic front-runner Hillary Clinton with time running out in the primary campaign.After winning the Democratic caucuses in Wyoming on Saturday, Sanders has now won seven of the past eight state contests. Still, to win the party nomination, he must take 68 percent of the remaining delegates and uncommitted superdelegates.The poll was conducted March 31-April 4, before Sanders and Clinton sparred publicly over who was best qualified to be president.Clinton gets unfavorable ratings from 55 per cent of Americans, while just 40 per cent have a favorable opinion. A whopping 69 per cent of Americans have an unfavorable view of Republican front-runner Donald Trump, and just 26 per cent have a favorable opinion.Among Democrats, 72 per cent have a favorable opinion of Sanders and 20 per cent have an unfavorable opinion. That's similar to Democrats' rating of Clinton. It has improved from 61 per cent who had a favorable view of Sanders in February, while his unfavorable rating remained stable.Twenty-three per cent of Republicans and 38 per cent of independents have a favorable view of Sanders, while 67 per cent of Republicans and 32 per cent of independents give him negative ratings. Just 7 percent of Republicans and 21 per cent of independents rate Clinton positively.About 61 per cent of registered voters say they'd at least consider voting for Sanders in a general election, while 38 per cent said they would definitely not. The percentage saying they would not vote for him is the lowest in the entire field. Fifty-one per cent say they wouldn't vote for Hillary Clinton, though she still does better than any of the Republican candidates on that measure. Sixty-three percent say they wouldn't vote for Trump.Sanders is the only candidate remaining in the field on either side who's viewed as at least somewhat honest, compassionate, civil and likable by a majority of Americans.Fifty-eight per cent say he's at least somewhat civil, compared with 48 per cent for Clinton and just 15 per cent for Trump. Likewise, 58 per cent call him at least somewhat compassionate, compared with 42 per cent for Clinton and 17 per cent for Trump.Though Sanders is more popular, Clinton remains the candidate viewed by the most Americans as able to win a general election, with 82 per cent saying she could capture the White House. Just 6 in 10 say that of Sanders or Trump.The AP-GfK Poll of 1,076 adults was conducted online using a sample drawn from GfK's probability-based KnowledgePanel, which is designed to be representative of the U.S. population.
