If you're following the US presidential elections, you may want to add another feed to your Google Reader. Google introduced a meta feed of shared articles for the McCain and Obama campaigns along with several political commentators. You can see articles that they've marked for sharing and any notes they've added.

The campaigns have so far left boring notes trying to direct readers to their websites, but the pundits often tell you why an article is important. I've added Power Readers in Politics to my list of Google Sources for US Presidential Election News.
