President Barack Obama’s challenge over the next year will be to boost his standing with four voting groups that helped him win the White Hosue.

Whites, women, younger voters, and liberals have turned away from him to certain degrees since his 2008 election.

An analysis of Associated Press-GfK polling shows that he’s got work to do with all of those voting groups.

They’re likely to be the top target of his 2012 campaign as he seeks to cobble together a coalition that’s diverse enough to help him win re-election in tough economic times.
