Two of the biggest political issues of the year are immigration and health care.
In the latest Marquette Law School Poll, 75% of Republicans said they were very concerned about illegal immigration and border security while 83% of Democrats said they were very concerned about health insurance. Those were the top issues among those groups. (Among independents, 79% said they were very concerned about inflation and the cost of living, making it their top issue.)
Here’s a look at some recent fact checks of claims related to health care and immigration.
Health care
No, Obamacare premiums aren’t doubling for 20 million Americans in 2026, but 2 to 3 million Americans would lose all enhanced subsidies and about half of them could see their premium payments double or triple.
Yes, Obamacare premiums increased three times the rate of inflation since the program started in 2014. They’re making headlines now for going up even more.
No, 6 million people have not received Obamacare health insurance without knowing it. There wasn’t evidence to back a claim by U.S. Sen. Ron Johnson, R-Wis., about the level of fraud in the program.
No, Wisconsin does not have a law on minors getting birth control without parental consent. But residents under age 18 can get birth control on their own.
Immigration
Yes, unauthorized immigrants have constitutional rights that apply to all people in the U.S. That includes a right to due process, to defend oneself in a hearing, such as in court, though not other rights, such as voting.
No, standard driver’s licenses do not prove U.S. citizenship. There’s a court battle in Wisconsin over whether voters must prove citizenship to cast a ballot.
Yes, U.S. Immigration and Customs Enforcement (ICE) is offering police departments $100,000 to cooperate in finding unauthorized immigrants. It’s for vehicle purchases.
No, tens of millions of unauthorized immigrants do not receive federal health benefits.

U.S. Rep. Tom Tiffany, the Republican front-runner in the 2026 race for Wisconsin governor, has a mixed record on statements fact-checked by Wisconsin Watch.
The northern Wisconsin congressman has been on target on some claims, such as low Wisconsin business rankings, the link between marijuana and psychosis, and a drop in Wisconsin reading scores.
Other assertions, including claims about tariffs, aid for Ukraine and vetting evacuees from Afghanistan, have been off.
Peer-reviewed research has found links between marijuana use and psychosis — the loss of contact with reality, experienced as delusions or hallucinations.
The consensus is there is a clear association, but more research is needed to determine if there is causation.
In August, Tiffany called for more research on the link to inform legalization policy.
Canada has set tariffs exceeding 200% for U.S. dairy products.
But the tariffs are imposed only when the amount imported exceeds quotas, and the U.S. “has never gotten close to exceeding” quotas that would trigger Canada’s dairy tariffs, the International Dairy Foods Association said.
Tiffany claimed that Wisconsin had “fallen behind” Mississippi in reading.
In the latest National Assessment of Educational Progress assessment, issued every two years, Mississippi’s fourth grade public school students scored higher than Wisconsin’s in reading proficiency, though the ratings “were not significantly different.”
In 2022, 33% of Wisconsin fourth graders rated “at or above proficient” in reading, vs. 31% in Mississippi. In 2024, Wisconsin dropped to 31%; Mississippi rose to 32%.
A $95 billion U.S. aid package for Ukraine, Israel and Taiwan, which President Joe Biden signed into law in April 2024, prohibits funds from being allocated to pensions in Ukraine.
Tiffany claimed that the law included “millions” for pensions in Ukraine. His office, pointing to a U.S. State Department news release, told Wisconsin Watch that Tiffany meant to say that previous U.S. aid packages funded Ukrainian pensions.
Following the Afghanistan evacuation that began in summer 2021, more than 76,000 Afghans came to the U.S. after being vetted, The Wall Street Journal reported.
All evacuees were brought to a military base in Europe or the Middle East, where U.S. officials collected fingerprints and biographical details and ran them through criminal and terrorism-related databases, the Journal reported.
In reviews, the Defense and Homeland Security departments found that not all evacuees were fully vetted.
Tiffany made the claim about changes the Biden administration made in 2024 to Title IX, a federal law that prohibits sex-based discrimination in schools receiving federal funding.
The new rules protect students and employees from sex-based harassment and discrimination. The rules say future changes will address sex-separate athletic teams.
As of late October 2023, when Tiffany made his claim, more than 200 non-U.S. citizens on the federal terrorist watchlist had tried to enter the U.S. between legal ports of entry and were stopped by Border Patrol during the Biden administration.
The watchlist contains known or suspected terrorists and individuals “who represent a potential threat.”
In making that claim, Tiffany cited a Wall Street Journal report on closed-door congressional testimony given by Devon Archer, a former Hunter Biden business associate, about Joe Biden participating with Hunter in about 20 phone calls when Biden was vice president.
The Journal quoted Republican Rep. James Comer as saying Archer testified that Joe Biden was put on the phone to help Hunter sell “the brand.” A transcript shows Archer testified that Joe and Hunter never discussed business on the calls.
Information cited by Tiffany when he made that claim in 2023 contained only unverified intelligence that the Ukrainian energy company Burisma paid Biden $5 million.
