I think the Obama admin is leaking all of this now on purpose. A quick recap:
1. After several months of stone walling on Benghazi, the Admin is now being fairly open even though their rhetoric would suggest otherwise.
2. EPA verifies that is hasnt targeted windmills for penalties from bird strikes like they have with almost any other industry, even though windmills kill more than 10x as many per year.
3. HHS confirms Sebelius is taking money from organizations to fund Obamacare prep.
4. AP phone records released to Justice despite DOJ not complying with its own procedures to do so.
5. IRS targeting conservatives.
I think the IRS is what triggered this and what will eventually carry the most weight. I think the Admin decided to let all of this leak now because of the timing in the election cycle. Why not let it all out now instead of the possibility of it becoming public this time next year. By the time the mid terms are in full swing, all of these issues will be gone and will not have a negative effect on the dems up for re-election.
The admin is clearing out its dirty laundry now in hopes of heading off any possible controversy coming into the midterms. I wouldnt be surprised to see a couple more low level issues come to light.
