Billionaire businessman Tom Steyer is leaning on a flood of Facebook advertisements in Nevada and South Carolina to gin up support for his presidential campaign ahead of the states’ forthcoming caucus and primary, respectively.

Steyer is far outpacing his 2020 Democratic rivals in Facebook ad spending in both states ahead of Saturday’s caucuses in Nevada and South Carolina’s primary on Feb. 29, according to data compiled by crowdfunding technology platform Booster that was first shared with The Hill.

Steyer has dropped more than four times the amount of money on Facebook ads in Nevada in the last 90 days than Sen. Bernie Sanders (I-Vt.), who spent the second-most out of the primary field in the state. Steyer spent $986,471 in Facebook ads in the Silver State in the past three months and $426,328 in the last 30 days alone.

The heavy spending comes as Steyer hopes for a strong finish in Nevada, the first nominating state to have a diverse electorate. However, despite his heavy expenditures, he finds himself stuck in the primary field’s middle tier in the state behind Sanders, former Vice President Joe Biden and Sen. Elizabeth Warren (D-Mass.).

Steyer was also left out of this week’s debate in Las Vegas after failing to reach the Democratic National Committee’s polling threshold.

The philanthropist is also opening up his deep war chest in South Carolina, far surpassing his Democratic rivals.

Steyer has spent over $1.5 million on Facebook ads in the Palmetto State in the past three months and $643,949 in the last 30 days. The spending has accounted for 68 percent of all dollars spent on the ads in South Carolina in the last 30 days among Democratic presidential contenders, according to Booster.

Former New York City Mayor Michael Bloomberg has spent the second most on Facebook ads in South Carolina, dishing out $179,182 in the past 90 days and $73,046 in the last 30 days.

Steyer’s campaign has cast South Carolina as a prime opportunity for him to break out, investing heavily on advertising on other platforms and filling his campaign staff there with a diverse set of local South Carolinians.

“Steyer has been laser focused on performing well in Nevada and South Carolina throughout this election as he captured 59% of Facebook ad spending in South Carolina and 56% in Nevada in Q4 according to our analysis,” said Booster co-founder Aaron Earls. “His polling in these states continued to increase late last year through to today according to Five Thirty Eight so his commitment to investing in these states seems to be paying off.”
