Mind you, the core of this argument is based on an ad run in a Republican political district I am in. A Democrat almost never stands a chance of getting elected here. Scott Murphy barely squeaked out a win by maybe less than 100 votes, and then lost by like 10%+ two years later to his GOP opponent, Chris Gibson.
Watch this ad being run again Chris Gibson's opponent this election:
Yes, there is "big spender" angle, but note the taxes. NO mention is maded of cutting taxes further, just holding the line. And also, see the line about Wall Street bonuses. Yes, this is an ad that went out that looked at executives getting bonuses in a negative light. And on budget cuts? Well, can't even mention cutting Medicare (in a SuperPAC email that arrived in the house in support of Gibson, it spoke out against cuts to Medicare). That is a political football. The GOP is actually running on the Democrats want to cut Medicare.
Pretty much, as it is now, maybe in some spots there can be pushing more for tax cuts, and also speaking on the "war on success", and also more cuts. But, when political reality hits, it isn't going to be able to get more done. As it is now, this talk of the 47% came out of giving everyone more tax cuts (bumping more out of the tax rolls) in order to cut taxes on the upper end. Reality is, people don't care about tax cuts for people doing better than them, if it doesn't benefit them. Even if the push now is to want to get more people paying taxes who aren't now on the lower end, so that more tax cuts on the higher end can happen. That just isn't going to play.
So, as it is now, the GOP is stuck. It can't politically push anything as an answer, because this has run the course. Unless they want to turn on budget deficits (this is a primary hammer being used to cut spending) and say "deficits don't matter", they are left holding the line. It is not "cut taxes more" but "prevent taxes being raised". And that there is being on the defensive.
