Young voters still approve of Obama, don't approve of how he's handling the issues

This seems to reflect what we've been hearing among all voters. Personal approval remains high while approval on specific issues is dropping.

What does this mean? Well it all depends on why you think people vote for a particular candidate. Primarily I think people vote for the man or woman, not their ideas. The voters want strong leaders with strong points of view, regardless of what those views are (within reason). Having said that, Bush was strong, and it worked for years, until his mismanagement caught up with him. Meaning, you can only get by on personal attributes for so long before voter perception of how you're actually handling the issues - whether the country is going in the right or wrong direction - catches up with you.

When does it catch up? It's not clear. It hasn't totally caught up with Obama yet. But it's still early. The trick is to either make enough "right" decision to keep the voters happy, or to get enough done early so that it doesn't matter.
