What's interesting is that normally, USAA (and other banks that tend to cater to government employees) will offer 0% APR loans to those who are impacted by this.
There have been quite a few reports of USAA not offering loans to those who are affected by this -- and other credit unions (NFCU) only offering $1000 as a quick loan...
If the banks don't want to deal with the risk of this until the shutdown is over, this makes me believe that the shutdown will last a while.
Interestingly enough, Congresspeople's staff are not getting paid during this break as well -- but the congressfolks are.
