They got nothin

The republicans will probably win a few seats in the Senate, but not enough to gain control.  The house will remain in their hands for a few more cycles, until the demographic tsunami they have helped create washes them out of power.  Meanwhile, they have nothing but Obama hatred to pump up their base.  The ACA, or as the pundits say, Obamacare has worked, so there is not much political capital to be gained by attacking that.  The economy has continued to grow and the job creation numbers are better than anything under the last couple of Republican Presidents so that's not a good line of attack.  As house guests pointed out last weekend, even with the slowly grinding economy, hotel rooms were at a premium on the NCR this past weekend and there were no events to draw tourists.  The events in Ferguson will probably fire up the Democrats base voters and without an appeal to racism, the repubs really can't make political hay out of the situation.   So, it comes down to tying every Dem candidate to Obama and hoping that is enough.
