NEW YORK (CBSNewYork/AP)-- Hillary Clinton says Bernie Sanders deserves credit for a "good night'' in the Wisconsin primary, but that he hasn't "done his homework'' when it comes to curbing gun violence or reining in Wall Street.
Clinton told MSNBC's "Morning Joe'' that Sanders' recent remark that gun dealers shouldn't necessarily be subject to lawsuits was "unimaginable'' because it put the rights of the gun industry above parents whose children have been killed by guns.
She said voters need to ask themselves whether he can deliver on his promises, including his pledge to break up big banks. She said none of what he has said about the banks "seems to be rooted in an understanding of either the law or the practical ways you get something done.''
Clinton is maintaining a lead of more than 200 delegates after Sanders' win in Wisconsin.
On Tuesday, Sanders netted about a dozen delegates, winning 47 to Clinton's 36. Three remain to be allocated, pending final vote tallies.
But his win wasn't big enough to make up much ground in delegates. Democratic contests award delegates in proportion to the vote, so more narrow victories do little to cut into a front-runner's big delegate lead.
Based on primaries and caucuses to date, Clinton now has 1,279 delegates to Sanders' 1,027.
The lead is even bigger when including superdelegates, or party officials who can back any candidate.
Clinton now has 1,748 to Sanders' 1,058. It takes 2,383 to win.
The candidates agreed to a Democratic presidential debate next week ahead of the New York primary. The televised debate will be held in Brooklyn on April 14, five days before the state's April 19 primary.
CBS2's Tony Aiello reported Wednesday Clinton campaign volunteers were making calls at Teachers' Union headquarters, looking to drum up support for the former secretary of state.
"She has always been with us and for us, both as a union and in terms of public education," Ann Rosen said.
Abe Levine said, "We're involved in a very important political campaign, and we'll come through for Hillary Clinton, I am sure."
An open mic picked up Clinton telling union members that "we got to get the energy going," as Sanders has been winning up to 80 percent of the younger vote.
"Bernie's message resonates with the people here and they trust him and I think that's one of the most important qualities New York is looking for," Chloe Malaise, a Sanders volunteer, said.
However, Sanders has not done well with minority voters, as his campaign is running an ad in New York featuring Eric Garner's daughter, Erica Garner.
"We need a president that's gonna talk about it. That's why I'm for Bernie," Erica Garner, whose father died while in NYPD custody, said in the ad.
Both candidates have personal ties to the debate site. Sanders was born and raised in Brooklyn. Clinton represented New York in the Senate and her campaign's headquarters is based in Brooklyn.
The Vermont senator outraised Clinton by $15 million in March and he says his television ad buy will be "significant" as he works for an upset in New York.
The most recent poll has Clinton up by 10 points in the state's Democratic presidential primary.
