The Democrats pushed for this. And it is a example of why Republicans occupy Congress and the White House. For how much sales taxes have increased over the years, have we seen a measurable improvement in government? I suspect most people would say no. Also, the Democrats will lie to you and say that the sunset provision will cause it to be temporary. But then they will ask voters to approve it since you are already paying for it. I see no net improvement in the government. 

You also will see Republicans vote to just lower taxes on the rich. Their proposals always cut the high rates and leave the rates that most people pay unchanged.

We have a government that tends to be inept and stupid regardless of which political party is in power.
