President Trump could face a tough re-election bid against a Democratic challenger come 2020, according to a recent CNN survey.

The poll conducted by SSRS shows potential 2020 contenders like Joe Biden and Bernie Sanders beating the Republican president by a wide margin. According to the survey, former Vice President Biden holds a 57 percent to 40 percent lead over Trump, while the U.S. senator from Vermont leads Trump by a 55 percent to 42 percent margin.

Trump's national approval rating stands at 44 percent with Rasmussen Reports as of Wednesday and at 36 percent with Gallup as of Sunday -- both figures that put him below where Barack Obama stood one year into his own presidency. Obama's approval rating was 49 percent with Gallup between Jan. 18 and 24 of 2010.

The new CNN poll also shows entertainment mogul Oprah Winfrey beating Trump by a 51 to 42 percent margin -- a survey result that comes after her fiery Golden Globes speech sparked speculation over a potential 2020 bid.

Biden has been anything but silent in criticizing Republicans and the Trump administration in his first year out of the White House -- weighing in via Twitter and on talk shows about the 45th president's Oval Office dealings.

Recently, Biden weighed in on Trump's reportedly naming Haiti and African countries as "shitholes," saying "we're better than this."

Others thought to be potential Democratic candidates come 2020 are Sens. Elizabeth Warren, Cory Booker and Kirsten Gillibrand.

This poll was conducted between Jan. 14 and January 18, 2018 among a sample of 1,005 respondents. The margin of sampling error for total respondents is +/-3.7 at the 95% confidence level.
