Not really. One thing we can be grateful for is that neither party really wants a default, because neither party is confident that it would be the electoral beneficiary.
It might seem that Republicans would get the benefit, but this fact in itself provides a reason for people to blame Republicans if things go bad, since they'll assume (as you appear to be doing) that they caused the default in order to get the benefit. This makes it pretty much a wash -- if bad things happen, both sides will blame the other and we can't quite see in advance how it'll all play out in the court of public opinion.
