I think in asking you I'd like to know what you think, but yes I think it does. It's a "compare and contrast" opportunity but rooting in reality instead of idealism, and it challenges Trump on the facts of which he has no command. He can use Trump's budget to scare the very people who support Trump and contrast it with his plan to help them. Again, any Democrat can do this but this is where Sanders' sincerity and independence and history is a real advantage. It's also one of the benefits of being the challenger and not the incumbent.
But his reaction to Bloomberg is all wrong. He should have contrasted himself (knocking on doors endlessly, caucusing with real voters in these states) with Bloomberg's blanketing of the universe with ads, and claimed he's more in touch with regular Joes than Bloomberg which is (a) true but (b) also worked for Bill Clinton vs. Bush (remember Bush marveling at the scanner at a grocery checkout?).
He does make this contrast but then adds, "That is the basic, fundamental problem of American society — is that billionaires have extraordinary wealth and power over the economic and political life of this country.” This is exactly what Trump does -- a lack of impulse control and a blaming of the "other" for the all the world's woes. He didn't need to say that, and if he really thinks that, he's the one who's out of touch. He thinks its part of his persona, but he's already got the people who believe that supporting him! He needs support from the people who DON'T. It's just dumb politically if he needs UNIFICATION and TURNOUT. I get we're still in the primaries but he has to start building those bridges now.
Sanders is more like Trump than Bloomberg is -- not politically but behaviorally.
