Things Are Starting to Get Ugly Between Hillary Clinton and Bernie Sanders

Judge Nap: Case Against Hillary Is 'Overwhelming, Damning and Grave'

O'Reilly: 'Hardcore Socialist' Bernie Sanders Will Never Be President

Sen. Bernie Sanders (I-VT) has responded to the recent spate of attacks by the Clinton campaign ... with some Simon and Garfunkel. 

The new ad's release this morning caused "Simon and Garfunkel" to be a trending topic on Twitter, and earned praise from political analysts. 

Democratic strategist Julie Roginsky said the ad was brilliantly executed and will appeal to millennial women.

"You don't have to be a Bernie Sanders fan or even a Democrat to appreciate the brilliance of that ad," she said.

The ad features the singing duo's iconic song, "America," over scenes of voters and Sanders rallies.

Sanders' campaign wrote on Twitter, "This campaign is not about Bernie Sanders, Hillary Clinton, or Donald Trump. This campaign is about you."

In his report from New Hampshire this morning, Ed Henry contrasted the positive message from Sanders with the tone of the Clinton campaign in recent days.

At a campaign stop last night, Clinton said Sanders wants a single-payer health care system that would require Congress to "start from scratch" on the issue.

Supporters of the former First Lady have been calling out Sanders' socialist views and arguing that he cannot win in November.

On the heels of the poll, a high-profile Clinton surrogate said that Sanders is not a Democrat, but rather a socialist with a lot of "wack-a-doodle" ideas.

Henry pointed out that Sanders will need to pick up more support from African-American voters when the Democratic race shifts to southern states.
