LOL. They already are targets of the media who have been scouring Alaska to get more dirt. Levi has been identified and had his picture circulated all over the globe. His appearance at the convention is an in-your-face response that shows responsibility and accountability. Keeping Levi closeted away is a sign of shame and embarrasment. Remember the old admonition that the cover-up is worse than the crime. This isn't a crime, but far better to confront the media head-on rather than try to avoid it and thereby stretch this thing out even further.
I am sure that Palin will address the issue tonight in her speech. The "Bristol Affair" will increase the audience size and energize the Rep base. There is a pony in there someplace.
It does keep the attention off issues such as illegal aliens. It also is distracting from issues. The Clinton years showed just how divisions personal scandals can be. The pregnancy could have been handled in a much better way.
