56. Read the whole article. It's more of an attack on Hillary than Bernie.

His numbers are more favorable.

From the article linked in the OP

Seventy-one percent of Democrats and Democratic-leaning independents hold a favorable view of Clinton, with 24 percent viewing her negatively. Sanders holds a similar favorability rating, with 73 percent of Democrats and Democratic-leaners rating him positively, and slightly lower unfavorables, with 18 percent rating him negatively. (Among just Democrats, Clinton’s favorability rating is 76 percent, with Sanders at 71 percent.)

Democrats and Democratic leaners say by a 10-point margin, 49 percent to 39 percent, that Clinton was not the party’s best option for a nominee last year. Fourteen percent say she was mostly to blame for Trump’s victory, with 37 percent calling her somewhat at fault, 24 percent saying that she’s not very much at fault, and 16 percent saying that she’s not to blame at all.

Looking forward, just 20 percent want to see Clinton run for president again, but 47 percent say they’d like to see her remain active in politics in other ways, while 23 percent want her to retire. Thirty percent want to see Sanders take another stab at the presidency, with 46 percent preferring him to engage in other facets of politics, and 12 percent wishing he would retire.
