President Donald Trump attacked Fox News again Friday after the right-leaning network’s latest poll showed him losing to all six of the leading contenders for the Democratic nomination.

“Worst Polls, just like in 2016 when they were so far off the mark, are the @FoxNews Polls,” Trump complained on Twitter. “Why doesn’t Fox finally get a competent Polling Company?”

Trump, who constantly shares Fox News clips and cites the network’s segments praising him on Twitter, has repeatedly lashed out over the network’s polling.

“Whoever their Pollster is, they suck,” Trump complained after a Fox poll showed a majority of Americans supporting his impeachment and removal from office.

“The Fox polls have always been lousy. I tell them they ought to get themselves a real pollster. But the real polls — if you look at the polls that came out this morning — people don’t want anything to do with impeachment. It’s a phony scam. It’s a hoax,” Trump ranted in November.

Trump has also complained when the network’s coverage was not laudatory, arguing that Fox host Chris Wallace “should be on Fake News CNN” and predicting “the beginning of the end of Fox” because the network dared to interview Democrats about his impeachment.

The latest outcry came after a new Fox poll showed him losing to every Democrat, even though 56% of respondents said they expect him to be re-elected — a 12-point increase since October.

Trump trails Sen. Bernie Sanders, I-Vt. (49% to 42%), former Vice President Joe Biden (49% to 41%), former New York Mayor Mike Bloomberg (48% to 40%), Sen. Elizabeth Warren, D-Mass. (46% to 43%), former South Bend, Mayor Pete Buttigieg (45% to 42%), and Sen. Amy Klobuchar, D-Minn. (44% to 43%). The poll sampled 1,000 registered voters and has a margin of error of 3%.

Even though a majority of voters believe Trump will be re-elected, 45% said they will definitely vote against him in November, compared to only 32% who said they will definitely vote for him. Even though voters think Trump will win, 65% said they think Sanders can beat the president. Respondents also said the same of Bloomberg (57%) and Biden (56%).

The Fox News poll showed some of the widest margins in the hypothetical head-to-head matchups, whereas other polls have shown tighter races. A CBS News/YouGov poll published earlier this week showed Trump losing to Sanders by 3%, Biden by 2% and Warren by 1%, while leading Bloomberg and Klobuchar and tying with Buttigieg. Last week’s ABC News/Washington Post poll showed Sanders, Biden, and Bloomberg leading by 5% or more while suggesting races against the other three candidates would be within the margin of error. An Emerson poll published last week showed that Sanders is the only Democrat who leads Trump.

Trump’s complaints about polling are not limited to mainstream surveys, Robert Maguire of the watchdog group Citizens for Ethics and Responsibility in Washinton (CREW), noted.

“Trump’s very big brain tells him he’s winning, so when polls call that into question his first reaction is that it must be the pollsters’ fault,” he wrote. “For instance, last year, when internal polls showed Trump underwater in key states, his campaign addressed it by firing the pollsters.”
