Romney Showing Signs of Fight and Obama Team Continues to Step In It

It's been an interesting day in the campaign and signs are showing that the Romney campaign knows how to fight back.  The Obama campaign brought up the old attack on Romney involving his dog on the roof of his car.  Then the Romney campaign gently reminded everyone that Obama himself ate dog at a young age.  The Obama campaign then mentioned that doing so was the equivalent of attacking a child.

In addition, Michelle Obama has invoked her father's battle with Multiple Sclerosis to show that they know what people struggle with in a sideways attack on the Romney camp.  Never mind that Ann Romney also suffers from MS.

What do you think of these things and does it show some hope in the campaign?
