WATCH: CNN unveils latest numbers from legendary Des Moines Register poll of the Iowa Caucus

Former Vice President Joe Biden has a slight lead in the 2020 Iowa Caucus, according to a new poll conducted by the Des Moines Register and CNN.

CNN announced the results on-air at 8 p.m. Eastern.

"According to a new Des Moines Register/CNN/Mediacom Iowa Poll of likely Democratic caucusgoers, 27 percent say Biden is their first choice for president. That’s down slightly from the 32 percent who said the same in December, but it tops the 19 other declared and potential candidates tested," the newspaper reported. "Biden has a 2-percentage-point advantage over Vermont Sen. Bernie Sanders. Though that’s within the poll’s 4.9 percentage point margin of error, other numbers bode well for the former vice president and suggest a stronger advantage over Sanders."

“If I’m Joe Biden sitting on the fence and I see this poll, this might make me want to jump in,” said J. Ann Selzer, whose firm conducted the poll. “I just can’t find much in this poll that would be a red flag for Joe Biden.”

"If Biden decided not to run, 30 percent of those who name him as their first-choice candidate would switch their allegiance to Sanders, whom they named as their second choice," the Register reported. "Among those who say Sanders is their first choice, 40 percent say Biden is their second choice."
