"Why should this woman vote for a party that will cut taxes she does not pay, but reduce benefits she does receive?"
If the poor had some sense even they would see that even without paying a dime of taxes they get taxed indirectly through the prices of what they must still actually purchase with those benefits, plus the pressure on the amount and availability of the benefits as taxation hits and passes the point of diminishing returns. Load the system too much and it crashes and burns. I'm a poet and I don't know it.
But again if they had more sense maybe they wouldn't be putting up with second best, with being poor and permanent parasites.
