Paul Krugman on how Donald Trump's ideas about the economy are a lot more popular with the Republican base than Jeb! Bush's voodoo/supply side economics, and going after him on that basis is going to make it difficult to cut into his popularity:
I’m not saying that everything is great in the U.S. economy, because it isn’t. There’s good reason to believe that we’re still a substantial distance from full employment, and while the number of jobs has grown a lot, wages haven’t. But the economy has nonetheless done far better than should have been possible if conservative orthodoxy had any truth to it. And now Mr. Trump is being accused of heresy for not accepting that failed orthodoxy?
So am I saying that Mr. Trump is better and more serious than he’s given credit for being? Not at all — he is exactly the ignorant blowhard he seems to be. It’s when it comes to his rivals that appearances can be deceiving. Some of them may come across as reasonable and thoughtful, but in reality they are anything but.
Mr. Bush, in particular, may pose as a reasonable, thoughtful type — credulous reporters even describe him as a policy wonk — but his actual economic platform, which relies on the magic of tax cuts to deliver a doubling of America’s growth rate, is pure supply-side voodoo.
And here’s what’s interesting: all indications are that Mr. Bush’s attacks on Mr. Trump are falling flat, because the Republican base doesn’t actually share the Republican establishment’s economic delusions.
The thing is, we didn’t really know that until Mr. Trump came along. The influence of big-money donors meant that nobody could make a serious play for the G.O.P. nomination without pledging allegiance to supply-side doctrine, and this allowed the establishment to imagine that ordinary voters shared its antipopulist creed. Indeed, Mr. Bush’s hapless attempt at a takedown suggests that his political team still doesn’t get it, and thinks that pointing out The Donald’s heresies will be enough to doom his campaign.
But Mr. Trump, who is self-financing, didn’t need to genuflect to the big money, and it turns out that the base doesn’t mind his heresies. This is a real revelation, which may have a lasting impact on our politics.
Again, I’m not making a case for Mr. Trump. There are lots of other politicians out there who also refuse to buy into right-wing economic nonsense, but who do so without proposing to scour the countryside in search of immigrants to deport, or to rip up our international economic agreements and start a trade war. The point, however, is that none of these reasonable politicians is seeking the Republican presidential nomination.
