Sen. Kamala Harris got some early positive feedback for her fledgling presidential campaign with readers of the progressive DailyKos blog.

The California Democrat topped the site’s new straw poll for 2020 candidates, released Wednesday. Harris’ 27 percent of the vote nearly doubled her total from a Jan. 8 survey.

Harris was followed by Massachusetts Sen. Elizabeth Warren, former Vice President Joe Biden, Vermont independent Sen. Bernie Sanders and former Texas Rep. Beto O’Rourke. Only Warren has announced that she’s running — so far.

DailyKos founder Markos Moulitsas has not endorsed a candidate yet, but says Democrats should nominate an all-female ticket, at least one of whom should be a woman of color.

“I think the nominee should be someone who represents the party’s base,” Moulitsas said in an interview.

The Democratic Party is, as its leaders like to say, a big tent, and respondents to the DailyKos poll are largely in the progressive corner of it. Outside that tent, Harris is still isn’t widely known.

A Morning Consult poll released Wednesday showed that 37 percent of the respondents had never heard of her and that another 19 percent had heard of her, but hadn’t formed an opinion yet.

While some people questioned the timing of Harris’ launch announcement Monday — on a federal holiday honoring the Rev. Martin Luther King Jr. — it seems to be paying off for her. The campaign pulled in $1.5 million in donations from roughly 38,000 donors within 24 hours of Harris’ announcement on ABC’s “Good Morning America.” That’s roughly the same as Sanders raised in a one-day haul early in his 2016 presidential run. Warren, New York Sen. Kirsten Gillibrand, former Obama administration official Julian Castro and Hawaii Rep. Tulsi Gabbard have not released how much they raised after the announcements of their exploratory committees this month.

Using the digital yardstick, there were far more Google searches of Harris than other Democrats who recently announced White House exploratory committees, including Warren, Gillibrand and Castro, according to the Washington Post.
