Damn, you'd think that someone at that level would pay for better OPSEC support. But then, I guess that I'm not surprised. Blackberry does have a reputation, not at all deserved at this point. I'm pretty sure that the President's phone is just as poorly secured. Probably less, from what I've read.
This issue is huge in politics. The entire Clinton personal e-mail scandal was essentially her unwilling to give up her BlackBerry, something Obama was unwilling to give up too. These people learned how to use some technology decades ago, and will continue using it no matter what other issues it causes.
The main scandal was her violating FOIA. There were some additional security concerns, but her running on a platform of undoing civil rights era legislation was the bigger issue.
