WASHINGTON • Spending in Missouri's U.S. Senate race this year won by Republican Josh Hawley surpassed $123 million, but Hawley's campaign spent less than 10 percent of that amount.

His opponent, Sen. Claire McCaskill, D-Mo., outspent him, $39.3 million to $11.3 million, according to their latest reports to the Federal Election Commission. McCaskill still had $468,000 cash on hand as of Nov. 26, Hawley $503,000. Subsequent reports are likely to add to the spending totals as after-election bills get paid.

But according to the latest analysis by the Center for Responsive Politics, the candidate spending was dwarfed by outside political groups that spent more than $71 million in the state.

Add the amount raised and spent by third-party candidates and those who lost in primaries, and the Missouri Senate race total exceeds $123 million, in what was the most expensive race in Missouri's history.
