As Donald Trump and Joe Biden prepare to face off in November, Forbes is tracking the billionaire money at play in the 2020 election.

A network of left-wing groups with budgets eclipsing those of conservative powerhouses like the Heritage Foundation will likely “carpet bomb” the 2020 election with anonymous dark money, a new report obtained by Fox News warns.

"If 2018 is any indicator, we should expect to see the Left carpet-bomb the 2020 presidential election with buckets of anonymous cash, while complaining about the evils of ‘dark money’ the entire time,” the report from conservative watchdog Capital Research Center says.

Federal prosecutors detailed the alleged foreign lobbying schemes carried out by Imaad Zuberi in a lengthy memo on Tuesday, alleging the Southern California campaign fundraiser who donated to Democrats and Republicans concealed work for shadowy interests around the world.

Dark money for me, but not for thee?

Socialist superstar Rep. Alexandria Ocasio-Cortez on Saturday began a fundraising push for her very own political action committee — despite her status as the party’s leading foe of big money in politics.

“We are pushing the envelope in DC by rewarding those who reject lobbyist money, fight for working families, & welcome newcomers,” AOC tweeted Saturday while announcing Courage to Change, a leadership PAC she set up within weeks of her 2018 election victory.

The campaigns of Republican and Democratic politicians frequently have worked in tandem with super PACs and other big-money organizations that are legally required to be independent from the candidates, says a report released Tuesday by nonpartisan reform group Issue One.

“We’ve seen a proliferation of political operatives, on both sides of the aisle, trying to outsource traditional campaign activities to super PACs and dark-money groups that can accept unlimited contributions from individuals, labor unions and corporations,” said Michael Beckel, Issue One’s research director.

The “green wave” of campaign cash that boosted Democrats and liberal causes in 2018 included an unprecedented gusher of secret money, new documents obtained by POLITICO show.

An expansive network of “shadowy” dark money donors has grown to rival the influence of the conservative Koch brothers -- pumping millions into left-wing causes ranging from health care to climate change to abortion -- all while flying well under the radar of public scrutiny, according to an explosive new report obtained by Fox News.
