Consider something along a different line.. Hillary is the key player in all of her scandals, vindictive and willing to take anyone down to protect or further her corruption. If she talks, all Hell breaks loose and a lot of people’s lives become irreparably destroyed.
Just suppose as insurance, Obama has decided that come Trump or not, he is safer with the main source of exposure silenced. We also know that there are a million and one ways to kill someone and make it look totally innocent, and it can be done quickly or drawn out for extended misery.
We know the Obamas and the Clintons hate each other. Without the main player in all this corruption, the whole issue can be swept under the rug and everyone had a close call but was finally saved by Hillary’s demise.
Remember Breitbart!
