That rush to credit the sequester ignores another line of revision in the OMB estimate resulting directly from the sequester: reduced revenue estimates. Because of the sequester's cuts that killed some jobs and blunted pay raises for many others, this line appears in the re-estimate:
The worse revision in the economic assumptions are of course essentially entirely due to the Republican sequester (or maybe in Speaker Boehner's words, they want to only take responsibility for 98% of it), resulting in $46 billion in lost revenue, just as it reduced $43 billion in spending. In other words, the seuquester raised the deficit by a slightly greater amount than cutting it. Folks, in Washington, that is known as the Republican version of fiscal responsibility.
