Another difference is that Bernie would like everyone to be able to afford at least one home without being saddled with insurmountable debt - fairer pay, fair lending, lower medical costs, and lower education costs can make it happen for more of us.
And to be super clear, to be a senator he’s required to maintain a residence in his home state as well as DC. And the cabin was his parents’ that they passed on to him. Really bullshit talking point and anyone still making it is uninformed.
