And even if they were low by U.S. standard, they're still much higher than other countries, and much higher than people would like. Imagine if someone responded like that to other issues:

"I think we should do more to reduce childhood hunger."

"Childhood hunger is already lower than it used to be, you must be a low information voter."

**

"I think we should do more to reduce traffic fatalities."

"Traffic fatalities are already lower than they used to be, you must be a low information voter."

**

"I think we should reduce carbon emissions."

"Carbon emissions are already lower than they used to be, you must be a low information voter."

If these are important issues for you, you're not going to want to be on the same team with the people who respond like that.
