DALLAS (CBSDFW.COM) – Democratic Presidential candidate Bernie Sanders downplayed concerns expressed by some in his party, that as a self-described Democratic Socialist, he is too far to the left to beat President Donald Trump.

“When moderates go to the polling booth, we will have 98 to 99 percent support of all Democrats because people are going to come together,” said Sanders.

Colton Ogburn said, “He stands for working class people and I think that’s something the Democratic party has lost site of. When people say Bernie’s not a real Democrat, I say Bernie is the most true Democrat.”

But Eddie Reeves, an undecided Democrat, said he knows who he won’t be backing in the primary: Sanders and Elizabeth Warren. “I’m just not sure they can get elected. At the end of the day, I think they haven’t yet found a way to appeal to a broad swath of the electorate they’ll need to get elected.”

Some of Sanders’ supporters have accused Democratic party leaders of rigging the system against Sanders.

At his rallies, Sanders has turned up the heat on the party.

When asked how concerned he is that the Democratic party establishment would try to prevent him from winning the nomination, Sanders replied, “Hey, that’s the story of my life. I’ve been taking on the establishment my entire life. Whether it’sWall Street or the drug companies or the insurance companies.”

Analysts say Sanders has the most loyal supporters of any of the Democratic candidates.
