the Two parties and spending

I read this from an article that talks about how much taxes need to be raised to balance the budget in 2020. it's kind of crazy how much.

here is a quote from it that i think sums up really well how the two parties work when it comes to spending and taxes. "Everyone favors benefits and opposes burdens (taxes). Republicans want to cut taxes without cutting spending. Democrats want to increase spending without increasing taxes, except on the rich. The differences between the parties are shades of gray."
I think that is right on.
Can we think of any other subjects that the two parties are just different shades of gray?
