Republican U.S. Sen. Cory Gardner and former Democratic Gov. John Hickenlooper spent more than three hours together in recent weeks trading attacks and making their pitches to voters. If you didn’t watch all three of their debates, here are some of the main takeaways to catch up on.

Lagging in the polls, Gardner is trying to make the race about character.

Voters in Colorado’s sprawling 3rd Congressional District have the choice of two very different candidates to represent them in Congress. The race is a clash between a young, political newcomer aligned with President Trump and a veteran state lawmaker who believes in pragmatism over polarization.

At 70, former state lawmaker Diane Mitsch Bush, D-Steamboat Springs, is more than twice as old as Lauren Boebert, 33.

The U.S. Postal Service has settled a lawsuit in Montana that called on it to reverse service cutbacks in advance of next month's election. The suit was brought by Montana Gov. Steve Bullock, a Democrat, who is running for the U.S. Senate.

In a statement, Bullock said the settlement "will ensure stability through and beyond the election by immediately restoring the mail services folks rely on."

The Postal Service said it agreed to the settlement because "it has always been our goal to ensure that anyone who chooses to utilize the mail to vote can do so successfully."

In their final U.S. Senate debate, Republican Sen. Cory Gardner and former Gov. John Hickenlooper clashed again over ethics, health care and the nation’s response to the coronavirus. But the candidates did not cover too much new ground in Fort Collins.

In one of their more heated exchanges, Gardner and Hickenlooper presented voters with very different views on environmental policy. Hickenlooper said he supports the country’s push to replace coal jobs with new ones promoting renewable energy.
