No, of course not. Who told you the economy was suddenly in good shape? Certainly not me, and certainly not any economist that I'm aware of. I'm unaware of the Obama administration saying it is in good shape either, it is simply in better shape than it was before. Our economy might look good in comparison to countries that were so irresponsible and foolish as to cut spending in a depression, but remember our modest austerity over the last several years only looks good in comparison to the disastrous results of more severe spending cuts in other western nations. Oh but yes, the behavior of the Republicans towards our economy has been nothing less than utterly irresponsible.
That being said, if you believe that the sequester is good fiscal policy then why not own it? You're doing the right thing for the economy, so why not be proud of your accomplishments?
The media has been telling me since 2011 that the economy is doing great. How many stories have played just in the last two months about how we don't have enough construction workers? President Obama himself told us long ago that he had fixed the private sector and now only needed to work on the public sector. (I'm sure we all know scads of government workers who have been laid off, right guys? Um, guys? Anybody?)
I actually do believe the sequester is good fiscal policy. It spreads the pain, forces fiscal restraint where none would otherwise be imposed, and may even spur some government agencies to look for ways to not waste money. I don't "own it" because since it was not my idea, that would be rude to President Obama. And austerity? Please! Total federal spending in 2003 was $2.16T (2012 equivalent dollars, 19.7% of GDP) with two wars going full blast. Total federal spending in 2011 was $3.60T (2012 equivalent dollars, 24.1% of GDP) with one war ended and one winding down. There is no rational definition of austerity that fits that behavior.

Perhaps Obama should have been more clear in proposing the sequester. Something like "I have a proposal, but I don't want to do it, and if we do do it then I want you guys to take the blame for anything bad, m'kay?"
