A new poll from NPR, PBS Newshour and Marist released ahead of Thursday’s Democratic presidential debate shows Massachusetts Sen. Elizabeth Warren taking the lead in favorability among Democratic voters, NPR reported Wednesday.

Results from the poll placed Warren ahead of both former Vice President Joe Biden, who has been considered a front-runner in the race, and Vermont Sen. Bernie Sanders.

According to the poll, 75% of Democratic voters say they have a favorable impression of Warren, compared to 71% for Biden and 66% for Sanders, says NPR.

Both Warren and Sanders have seen an increase in voters with favorable views since January, the last time NPR released poll findings about Democratic candidates. Biden, on the other hand, has seen his results decrease by 5% in this area since January.

Results are more mixed when it comes to general voters, however. NPR reports that this new poll places Biden at 45% among all registered voters, with Warren trailing at 41% and Sanders at 38%.

Thursday’s event will be the first time that Warren, Biden and Sanders find themselves on the same debate stage. The debate will feature 10 Democratic candidates in total, as reported by the Deseret News.

According to PBS, the poll also asked Democratic voters about their priorities in the 2020 election. Respondents were asked to choose between a candidate who represented their values, versus someone who had the best chance of winning the race against President Donald Trump.

Given these two options, 58% of Democrats and left-leaning independents said they would prefer someone who can win in 2020, PBS reported. This is up from June, when 46% said they preferred someone who can win.

When asked about Trump’s performance as president, 25% of American voters said they strongly approve, while 45% said that they strongly disapprove.
