Democratic presidential candidate Bernie Sanders shot back over the Washington Post, after the publication published a scathing editorial about him.

Although he was reserved on expressing his disappointment with the op-ed piece, Sanders noted that what the Washington Post, along with his other detractors have said was far from new.

Sanders said, "That's not a new argument." The Vermont senator then added that he and his campaign have been hearing those arguments for months, saying that their plans and proposals if he becomes president is too radical and totally unrealistic, Business Insider reported.

He said, "Our ideas are too ambitious -- can't happen. Too bold, really?"

Sanders then shot back and recalled the publication's support of the Iraq invasion and then defended himself and said that despite what many thinks, he's not as radical as they perceive him to be.

According to a report by Alternet, the Washington Post was on the offensive lately and the recently published op-ed piece is actually the second time the publication has attacked the Sanders campaign.

The publication first criticized Sanders' proposal of a single-payer tax plan, but now turned its attention to the whole campaign in general and accused it of selling "fiction" to American voters.

According to the Post, "Mr. Sanders's tale starts with the bad guys: Wall Street and corporate money. The existence of large banks and lax campaign finance laws explains why working Americans are not thriving, he says, and why the progressive agenda has not advanced."

It countered that despite senator's criticism of the so called "big banks," Wall Street have already undergone numerous reforms that prevents it from milking the financial system.

The publication also added that despite Sanders' sincere intention, it still thinks that it will face opposition to the general American voters and their representatives.

It went on to call Bernie to be like many other politicians, guided by strong ideological preferences, but turns back when it's inconvenient for them.

The Washington Post then said that Sanders has yet to show that America is ready for a political revolution, and is just pandering to the liberal crowd.

Many defended the Vermont senator and noted that the Washington Post is attacking the Bernie campaign out of personal interest of keeping the status quo.

As noted, the Washington Post is owned by Jeff Bezos, a businessman who founded Amazon and is worth $53.2 billion and has many investments in private health care.

Sanders currently ranks second to Hillary Clinton with the Iowa caucus is just days away.
