If you're going to run up a deficit, now is as good a time as any. Just as there are a lot of home buyers and refinancers taking advantage of the near 30+ year low mortgage interest rates; likewise the bond yields are near 30+ year lows. Now is a good time to borrow money. This is in stark contrast to when Ronald Reagan ran up his deficits- back then the bond yield was between 10-15%!!!! Now that was a terrible time to run up a deficit.
