Please don't move the goalposts. While they're of course inextricably linked, I'm talking about the issue of "reckless borrowing", i.e. that stuff we have to pay interest on.
And I don't care so much how they're trending down as how they're still above a trillion dollars. By the same token, should we give Bush and the Republican Congress credit for reducing deficits 2005-7? With 2007 still above 2002..?
As for spending, debt etc. being an issue, while it certainly matters what "Republican politicians" say and do, "conservatives" and libertarians have been raising as big a fuss about it as we can since the days of Nixon, and I gather longer (I became politically aware during his Administration so I can only vouch for it starting then).
