When he's not bragging about the 100,000 tens of thousands thousands possibly dozens of jobs he created at Bain Capital, Mitt Romney has been saying that in his first term as president, he'll get unemployment down to 4%. But like his job creation numbers, Romney is backing up on his unemployment numbers, too, according to Talking Points Memo:

“I can tell you that over a period of 4 years, by virtue of the policies that we put in place, we get the unemployment rate down to 6 percent, or perhaps a little lower,” Romney said, “depends in part upon the rate of growth of the globe as well as what we’re seeing here in the United States, but we get the rate down quite substantially.”

Given that we’ve been hovering near eight percent for months, that sounds like a major improvement. But many models — including the one used by Congress’ non-partisan budget and economic scorekeeper — suggest we’ll reach that level whoever happens to be president. The table on page 129 of CBO’s 2012-2022 outlook forecasts an average unemployment rate of 5.8 across fiscal year 2017, which begins October 1, 2016, just shy of four years after Romney’s hypothetical inauguration.

So now Romney is promising he'll lower the unemployment by two percent in four years. By some metrics, the unemployment rate has lowered almost three points in the last two years under President Obama.
