As we get nearer to the election and things start looking very bleak for the Rats, there will be either 1) another delay in the employer mandate and/or 2) a push by Rats to entirely repeal the employer mandate. Robert Gibbs signaled his support for 2) a few days ago.
Anything to avoid a complete slaughter in the election will be done.
The truth is that there won’t be a repeal of just the employer mandate with a GOP House. They’ll load up any bill with all sorts of poison pills that will destroy any chance of the Dem Senate from passing it.
