An absolutely critical issue, which impacts almost every other issue, and which no administration (Democrat or Republican) has handled well or is particularly excited about debating.
It is due to this that issues like Gay Marriages and Indecency and Spam E-Mails get undue prominence by pol's in the usually successful hope of distracting the voters.
And does it ever work.
If you doubt me, just take a look at the comments and ratings on this list.
