Nearly half of voters say they're unsure who won Detroit debates

Almost half of voters polled — 47 percent — say there was no clear winner from last week’s Democratic presidential primary debate in Detroit, according to a new Hill-HarrisX poll.

However, among just Democratic voters, Harris still maintained fourth place at 4 percent, with Sen. Corey Booker (D-N.J.) rounding out the top five at 3 percent. Gabbard trailed behind both candidates at 2 percent. 

The survey comes less than a week after the second round of Democratic debates.

Top-tier candidates Sanders and Warren were widely seen as having emerged as the clear winners from the first night of debates. Together, the two progressive leaders fended off attacks from centrist Democrats over progressive issues like "Medicare for All."

However, the picture was more muddled the following night when the party’s divisions were on full display.

Beto O’Rourke (D-Texas) were seen as having had weaker performances.

During the debate, Gabbard said she was “deeply concerned” about Harris’s record as California attorney general, accusing her of locking up people of color for low-level drug offenses, hiding evidence that would have freed an innocent man on death row and fighting for long sentences to use prisoners for cheap prison labor.

“The people who suffered under your reign as prosecutor, you owe them an apology,” Gabbard said on the debate stage.

Harris in turn said she was proud of her record and took a jab at the Hawaii congresswoman, saying she hasn't spent her career giving "fancy speeches," but "actually doing the work" in a real world environment. 

Gabbard became the most-searched candidate of the second night following the tense exchange, and the two continued to spar over the issue the following day.

Gabbard’s campaign also announced on Friday that it had reached the necessary 130,000 unique donors to qualify for the September debates in Houston. However, she has yet to reach the polling threshold as required by the Democratic National Committee.

The Hill-HarrisX poll was conducted August 3-4 among 1,001 registered voters with a margin of error of plus or minus 3.1 percentage points.
