Trump supporters like to think that Trump does really well with independents, but opinion polls indicate otherwise

And position on the spectrum isn't what decides Hillary's support - otherwise, Iowa would have favoured her much more strongly. New Hampshire opinion polling has Sanders ahead 54% to 40%. And let's be honest - it's unlikely that the remaining 6% are going to go to Hillary, because she's too well-established; if they were going to support her, they'd already be doing so. And keep in mind, many independents aren't centrist, they just don't align well with the two parties. One thing to note is that, in terms of alignment on the left/right spectrum, both parties have drifted to the right over the last 20 or so years. That means that more independents lie to the left, and fewer to the right.
Of course, that link suggests Trump will also have the strongest support; the difference is, where it's a two horse race on the Democratic side, it's an 8-sided brawl on the Republican side. Trump is likely to do better in opinion polls than in actual primaries, especially in New Hampshire, where voters tend to make a final decision relatively late. And because of how they run their primaries, it's even more true than that.
Sanders supporters, even amongst independents, tend to be pretty specifically in favour of him - that is, they're supporting him because he's him, because of his politics. Trump's supporters amongst independents are mostly supporting him because he's an "outside" candidate, because he speaks "like them", etc. What does this mean? It means that, when independents choose whether to vote on the democratic or republican side (as they get to choose which primary they vote in), Sanders' supporters will vote on the Democratic side because they're specifically in favour of him. Meanwhile, Trump supporters will see Trump as a shoe-in to win anyway, and will want to weaken Hillary Clinton by voting for Sanders on the Democratic side, as Sanders is far less "establishment" than Clinton.
Early numbers from the towns that have already completed their primary voting have Cruz, Kasich, and Trump all equal, and Sanders with a strong lead ahead of Clinton. It's a tiny sample, and not at all unbiased, but it kind of demonstrates my point, nonetheless.
