Sen. Lieberman: The negative tone of campaign is 'exactly the opposite of what the country needs right now'

The presidential candidates are hitting the campaign trail again today, with Mitt Romney in Chicago and President Obama set to have back-to-back fundraisers in Washington.

The president may have a new catchphrase to use tonight after he took a jab at Romney's tax plan while addressing supporters in Connecticut yesterday.

Calling the candidate's proposals "Romney Hood," Obama insisted that Romney's tax plan "is like Robin Hood in reverse."

Senator Joe Lieberman weighs in on the negative tone of the 2012 presidential campaign on Starting Point this morning.

"The campaign has already set records for nastiness and negativity," Sen. Lieberman says. "It's exactly the opposite of what the country needs right now. We need a healthy dose of vision."

Sen. Lieberman's book "The Gift of Rest" is currently being re-released in stores.
