What opinions would you have liked him to change? Considering the opinions he is consistent on, I see that as an asset rather than a Corybn idealistic arrogance. I prefer a man with honourable consistency to an expert shape shifter controlled by big money but each to their own.
Ultimately he (Sanders) seems to lack realism, or pragmatism. Revolution rarely works - incremental change is usually the way to go, and I don't think Sanders is going to provide that. Also - and here's a big problem in the context of a US election - Sanders is an unabashed Socialist. Which is a dirty word for many Americans.
I know it's boring to hear but something really does need to happen in regards to the wealth gap and soon.

Capitalism has been the single most effective weapon in the war against poverty (graph sourced from here
It's really easy to make the mistake of assuming that wealth inequality is the same thing as standards of living
The Oxfam report that was published this week is a particularly egregious example:
Credit Suisse’s annual Global Wealth Databook, Oxfam’s primary data source, uses so-called net wealth, defined as “marketable value of financial assets plus non-financial assets (principally housing and land) less debts.” By that standard, an American with, say, a high salary and a large mortgage might—if the amount owed on the mortgage is greater than his assets—be counted as less wealthy than a subsistence farmer who doesn’t owe anything.
Who'd you like to be? An American "suffering" high levels of Wealth inequality, or a subsistence farmer who owns a bicycle?
