Democratic tv debate had barely started Thursday night local time, before the ten candidates on the stage, the smoke at each other’s throats.

The two frontrunners, former vice president Joe Biden and senator Elizabeth Warren, duellerede on the issue of health insurance.

Joe Biden, 76, criticized warren’s plan to ensure the public health insurance called medicare for all.

Biden said that instead he will build on president Barack Obama’s health care reform, Obamacare, which means that people can keep their private insurance if they prefer it instead of a public.

– in my opinion, seemed Obamacare, says Joe Biden in the debate, which was held in Houston, Texas.

Elizabeth Warren, who is promoted to second place in the polls, praised Obama’s action on health, but pointed out at the same time:

– the Question is now, how we can best improve it.

Bernie Sanders agreed with Warren and said that medicare for all is the most cost-effective solution.

Pete Buttigieg, a 37-year-old mayor from Indiana, counselled for calm and reminded the warring parties that the main enemy is Donald Trump.

– It is exactly this which makes people are tired of politicians, he says.
