Good suggestion in this thread. Here are a couple sites for left-leaning folks:
<a href="http://intl-news.com/">Intl-news.com</a>
<a href="http://www.americanprogress.org/">American Progress</a> (esp. the Daily Progress Report)
<a href="http://www.alternet.org">AlterNet</a>
<a href="http://www.truthout.org">Truthout</a> (I know someone already mentioned it, but it's worth another nod).
Happy browsing.
