Biden urges Harris to 'go easy on me, kid'

Detroit: Democrats intensified an acrimonious battle over health care on Wednesday that showcased deep divisions within the party and focused on the dispute between former Vice-President Joe Biden and California Senator Kamala Harris.

Their divisions were reinforced by their ideological allies from the progressive and moderate wings of the party, with New Jersey Senator Cory Booker trying to play the role of peacemaker.

Biden charged that Harris' plan would cost $3 trillion even after two terms in office and would force middle-class taxes to go up, not down. He said that will put Democ-rats at a disadvantage against President Donald Trump. "You can't beat President Trump with double talk on this plan," he said.

Harris slapped back that Biden was inaccurate. "The cost of doing nothing is far too expensive," Harris said. She added: "Your plan does not cover everyone in America."

The tense exchanges came early on the second night of Democratic debates that pitted the 76-year-old Biden against a younger slate of more diverse candidates. There were no candidates of colour onstage in the first wave on Tuesday. On Wednesday, there were four.

Biden was flanked by Harris on one side and Booker on the other. As Biden greeted Harris onstage moments before the opening statements, he quipped, "Go easy on me, kid."

Wednesday's debate comes 24 hours after another set of 10 Demo-crats debated, fiercely at times, over the direction of their party.

In that encounter, Bernie Sanders and Elizabeth Warren faced intense criticism from lesser-known moderates who warned primary voters that a sharp shift to the left on health care and other key policies would make it all but impossible to defeat Trump.

That same dynamic will be on display Wednesday night - only in reverse. Biden, who leads virtually all early polls, is considered the premier moderate on stage. In addition to Harris and Booker, his more progressive opponents include New York Mayor Bill de Blasio, former Obama administration housing chief Julian Castro, Hawaii Rep. Tulsi Gabbard, New York Sen. Kirsten Gillibrand, Washington Gov. Jay Inslee and entrepreneur Andrew Yang.

While the first primary votes won't come for six more months, there is a sense of urgency for the lower-tier candidates to break out. More than half the field could be blocked from the next round of debates altogether - and possibly pushed out of the race - if they fail to reach new polling and fundraising thresholds implemented by the Democratic National Committee.

The dire stakes have forced many Democrats to turn away from Trump and turn against one another in recent weeks.

Diversity was an early focus.Biden said Trump was tearing at the "fabric of America" and highlighted the value of diversity in his opening statement.

"Mr. President, this is America," Biden said of the diverse slate of candidates on stage.

Harris also referenced Trump's divisive presidency. "This becomes a moment we must fight for the best of who we are," Harris said. "We are better than this."
