Democratic presidential candidate Sen. Elizabeth Warren received a boost in polling that pushed her above Vermont Sen. Bernie Sanders.

While both candidates have been campaigning with similar platform promises of "Medicare for all," college debt forgiveness, and the end of political lobbying, the poll conducted by Morning Consult/Politico shows that Warren, 70, has picked up 13 polling points since April, while Sanders, 78, has lost five.

Though Warren still trails front-runner Joe Biden, 76, by a significant margin in the poll, her bump in numbers puts her solidly into second place above Sanders since Morning Consult/Politico began tracking the candidates in January.

The Massachusetts senator still faces an unknown factor with black American voters, 40% of whom support Biden in the current data, though 29% of black respondents said they had not yet decided on a first choice for Democratic candidate.

Though Warren's rise in popularity is significant, she still trails Biden in every major demographic category. However, Biden gained only two percentage points since Morning Consult/Politico conducted the same poll in April compared to Warren's 13 point gain. Sanders has slipped by five points over the same period.

The current RealClearPolitics polling average, which surveys all major political polls, reflects a similar rise in popularity for Warren with 19.2% of the vote, trailing Biden, who has 30.3% by just over 11 points.
