Across the state of Wisconsin, Republican Leah Vukmir and Democrat Tammy Baldwin are each hoping their message to voters will make them a voice in Washington.
An issue that's emerged in this race is healthcare. Senator Baldwin said that the Affordable Care Act has some flaws but also has parts that must be protected.
"We have to build it up and fix it, but we can't throw away people's protections for coverage for pre-existing conditions - ever," Baldwin said.
Vukmir supports a full repeal of Obamacare.
"Right now, Obamacare is failing," Vukmir said. "It has absolutely been an utter failure. Skyrocketing premiums, people have lost their doctors and their health plans."
She said that health care needs a patient-centered, free market approach. Vukmir also said that she supports coverage for people with pre-existing conditions. Baldwin's team disputes that claim.
Another issue of debate is immigration. Vukmir is siding with President Trump.
"The chaos that's about to ensue at the border, people are fed up, they're frustrated, they really stand with the President and want to be sure that we have a wall built for border security," Vukmir said. "I stand with the President on that."
Baldwin said that the immigration debate shows a broken system that needs fixing.
"A comprehensive plan would create a path for citizenship for our dreamers and others," Baldwin said. "I voted on such a plan in 2013, my first year in the United States Senate."
Baldwin said that as time goes by the focus stays the same - the desire to fight for Wisconsinites. For the challenger Vukmir, she wants to bring the Wisconsin way to Washington.
