Why don’t you just defeat Rep. Day the next time she runs for office and let her know that’s what you’re going to do?
In New Hampshire we have districts where multiple representatives are selected in one election. In Rep. Day's district there are 8 representatives. So the top 8 vote getters win. In that situation it is hard to defeat a single candidate, particularly when there are a flood of Democrats running.
But you can be sure voters and activists in that district will try to unseat her the next time around. As well as every other representative who supports or votes for the bill.
