Both campaigns are focusing their digital efforts on the economy.

WASHINGTON (AP) -- A new report says President Barack Obama has an advantage over Republican Mitt Romney when it comes to reaching voters online.

The Pew Research Center says Obama has been more aggressive about communicating through digital and social media platforms. During a two-week period in June, Obama's campaign tweeted an average of 29 times a day. Romney tweeted about once.

Obama's team has also been more active on YouTube, blogs and photo-sharing sites.

Romney's digital director, Zac Moffatt, says more is not always better. He says the campaign is working to get voters to engage in an online conversation - not just to read campaign posts.
