Obama wasn't 'blindsided' - he is just trying to shift the blame to those evil 1%er loving rethuglikkkan supporting insurance companies. -This is just a replay of the same thing that happened with fuel prices. -Obama wasn't upset that fuel prices rose, just that they rose too fast.
In this case, Obama isn't upset that these polices are getting cancelled - just they are getting cancelled all at once.
This was no surprise, Pitt. -Now that 'the cat is out of the bag' , several Obamacare supporters have made it clear that these cancellations need to happen, else Obamacare dies. Even us stupid Teabaggin' Freepers knew it from the beginning, so it had to be obvious, right ?
