"I can tell you that over a period of four years, by virtue of the policies that we'd put in place, we'd get the unemployment rate down to 6%, and perhaps a little lower," the presumptive GOP nominee said in a TIME interview published Wednesday.

One problem with that…. based on the current rate of growth, the jobless rate is expected to fall to around 7% by the end of 2015, and 5.5% by the end of 2017, according to reports by the bipartisan Congressional Budget Office. 

So if it is 6% by 2018, it will be half a percentage higher than without Romney.
