patrick healy, you wrote in the "new york times" today, despite the urging of some advisers, mr. sanders refused last fall and early winter to criticize mrs. clinton over her $675,000 in speaking fees from goldman sachs, an issue he now targets almost daily. he also gave her a pass on her use of private e-mail as secretary of state, even though some allies of his wanted him to exploit it, and he insists on giving time to his time as senator. tad devine, by the way, responded to your report today in an interview with andrea mitchell. here he is. >> my first talked to them about this a couple weeks ago. i think they were determined to write a story if bernie sanders had run a tough, negative campaign, he could have defeated hillary clinton. he was never going to run that camppign. that's not who he is. >> what inspired you to write a story about what might have been last year or earlier in the campaign? bernie is doing pretty well right now. why go back to what coulda wooda shoulda happened. >> that's comaktly it. he's doing really well right now. the reality is that he's still far

patrick healy has some fascinating reporting on this story.roke this wide open over the weekend. why don't you tell us first off what you found. >> sure, john. so they're at an early stage but they're compiling a list of about 15 to 20 names. in conversations with hillary clinton, with bill clinton, with john podesta, the campaign chairman. they will take that list of about 20 people and they'll ultimately do a vet of probably about five or six people that could start as soon as she clinches the nomination. now, that could come if all goes according to their plan as early as mid-may and then they will start this vetting process which is a really deep dive into the lives of five or six people. hillary clinton's made clear she wants the initial pool of 20 to reflect the diversity of the party, of her supporters. they expect a couple of african-american democrats to be in that pool, a couple of hispanics. also a couple of women. >> how real is the possibility from your conversations and what you're hearing of an all-female ticket? >> kate, it's l

patrick healy is a "new york times" correspondent covering the campaign as well, and here with me inwaukee is u.s. congresswoman gwen moore. she's from this area of milwaukee and she's supporting hillary clinton. >> kasie, it all seems within the margin of error out here in wisconsin on both sides. >> hey, chris. yeah, forgive me. i can't hear you terribly well because what's going on here is a rave or a concert, i can't really tell exactly what. we're waiting for bernie sanders. he obviously is pretty confident going into this. you talked a little bit about, showed what he had to say earlier. i think there is a little bit of danger here in the expectations game for bernie sanders. at this point, we're looking at the margin of his win, and if hillary clinton can plausibly argue after tomorrow's results that she held her own, that this wasn't a significant win, remember, for bernie sanders to catch hillary clinton in this delegate lead, he has to win states, and he has to win them big, by margins of 60% to 40%. and their argument is going to be if he can't do that in wisconsin, where
