I have expressed misgivings over the debt ceiling legislation because of the potential for the Joint Committee to come up with tax increases as one of the ways to cut the deficit,
as is required in order to avoid sweeping across-the-board cuts.
Note, however, that there's a decent argument (set out here
, by the WaPo's Jennifer Rubin, whose reporting on this entire affair has been stellar) that budget scoring rules make it very difficult to reach the necessary savings through tax hikes.
Read and evaluate for yourself.
