He's worked across the aisle with Republicans on a few issues, but to be fair I don't see Bernie or Hillary being successful at pushing anything through Congress if it's still divided.
For Clinton and the best situation with a divided Congress, the most I can see is possibly some mediocre form of paid leave - Something clearly recognizable as having been tainted by pro-business conservative politicians, though. Anything else would likely be small in both nature and impact on the budget (including infrastructure dev)
While I agree Sanders has worked on some issues like that before, he would probably be like Obama on steroids to the Republicans. Significantly more liberal and more aggressive about it, while actually being a type of socialist (rather than Obama just being called that). The GOP would go absolutely 100% crazy over his election. McConnell would be uttering "Our number one priority is to make Sanders a one term president" in his sleep incessantly.
However, all things considered, Sanders achieving any of the proposals his supporters drool over is completely out of the question. They would probably remember him as that nice guy who failed to achieve anything despite making it all seem possible.
I agree, some of his bigger proposals like his health care plan would need the success of a major down ballot victory for Democrats which would give them control of Congress (if that even). I still think both of them would have an equally hard time getting much done through Congress now, even if Democrats just won back the Senate. Sanders definitely has more Congressional experience though, where I could see it working to his advantage.
