It resonates with the voters of her state. She doesn't care if YOU think it's stupid. The unionists and the liberals in Massachusetts love **** like this, and so she spoon feeds 'em.

Turn your ire on those who VOTE for them. Otherwise, you're like the dogs barking at the caravan. The caravan moves on heedless.
