When I was still registered Republican (it's pretty much the default party of my state), my idea was more "tax control" than "tax cut". You know, actual fiscal conservatism, not fiscal brinksmanship. You know, find a need. Can we cover it with existing taxes? Okay, don't raise taxes. Do we need more money for it? Construct a new tax that will help pay for it and spread out the cost effectively as possible.
The eternal "tax cuts forever, and more cuts on top of the ones we already have" sound good in campaigns but are irresponsible and costly. Around here, people insisted on blocking and cutting taxes. Much like the GOP. The city came back and said okay.. but now we have to shut down all the swimming pools a month early, because we don't have the money. Much like we just closed our parks. And now the GOP is whining the parks are closed... much like people bitched the pools were now closed. They want tax cuts but keep all the 'nice' stuff at the same time, and it's just impossible to do that. If you want nice, you have to pay for nice.
The Tea Party wants nice without having to pay for it. At either the funding or the tax paying level.
And this has always been the fundamental flaw with Republicans. "We want less government!" Ok, so you don't want public roads or schools or benefits?
"We want less taxes!" Ok, so you don't want us to pay for anything you use, more or less.
I'll never understand the mindset that goes behind this. This is third grade math here. If you're using more than you're getting, you're at a negative.
