President Trump on Monday dismissed a new poll from Fox News that showed him losing to multiple 2020 Democratic presidential candidates, saying “something weird” is happening at the network favored by conservatives.

Fox News on Sunday released a poll that showed Trump trailing five Democratic presidential contenders in hypothetical 2020 match-ups. The survey showed former Vice President Joe Biden leading Trump by 10 points.

It also showed Sen. Bernie Sanders (I-Vt.) carrying a 9-point lead in a hypothetical head-to-head match-up. Three other Democratic candidates — Sen. Elizabeth Warren (D-Mass.), Sen. Kamala Harris (D-Calif.) and South Bend, Ind., Mayor Pete Buttigieg — also polled ahead of Trump, albeit within the survey’s margin of error.
