Okay, here is what Democrats can say when Republicans accuse them of raising taxes (after the Republicans have lowered them inappropriately):
Let's say your little children were used to going to bed at 7:00 in the evening and for some crazy reason everybody got it in their head they should stay up later. So they start going to bed at 10:00 at night. Pretty soon everyone is crabby, the kids aren't learning anything at school, and no one has a moment's peace. So the grownups set the bedtime back at 7. Everybody starts getting enough sleep again, and things work a lot better.
Republicans and taxes are like children and bedtime. They want what's fun for them, not necessarily what's good for them -- and what's good for the whole family.
