(AP) The 2022 elections are on track to cost $16.7 billion at the state and federal level, making them the most expensive midterms ever, according to the nonpartisan OpenSecrets.

For perspective: The contests will nearly double the cost of the 2010 midterm elections, more than double the 2014 midterms and are on pace to roughly equal the 2022 gross domestic product of Mongolia.

At least $1.1 billion given at the federal level so far this election season has come from a small coterie of donors, many of whom have favored conservative causes.

“When you look at the top 25 individual donors, conservativedonors heavily outweigh liberal donors by $200 million,” said Brendan Glavin, a senior data analyst for OpenSecrets. “There’s a big skew.”

Tech billionaire Peter Thiel ($32.6 million), shipping goods magnate Richard Uihlein ($80.7 million), hedge fund manager Ken Griffin (68.5 million) and Timothy Mellon, an heir to to a Gilded Age Fortune who gave $40 million, are among the top conservative donors.

On the liberal side, hedge fund founder George Soros gave the most ($128 million), though much of it has yet to be spent. Sam Bankman Fried, a liberal 30-year-old cryptocurrency billionaire, gave $39.8 million.
