FOUR more years of a Trump presidency became more likely today, after Bernie Sanders dropped out of the running for the Democrat presidential nomination.

His campaign announced that he was suspending his bid to run against US President Donald Trump in November’s election, handing former vice president Joe Biden a clear path to secure the party’s nomination.

In a special message broadcast from his campaign website, Mr Sanders paid tribute to his supporters.

He said: “Not only are we winning the struggle ideologically, we are also winning it generationally.

“The future of this country is with our ideas.”

But he said that, after much consultation, it became clear that it was impossible to secure the Democrat nomination.

“I cannot in good conscience continue to mount a campaign that cannot win,” Mr Sanders lamented.

“While this campaign is coming to an end our movement is not.”

Quoting Dr Martin Luther King, Mr Sanders said: “The arc of the moral universe is long, but it bends toward justice.”

He said that he was now backing Mr Biden, who he described as “a thoroughly decent man” to take on “the most dangerous president” in US history.
