Less than five months until the big November election and both parties are already making a lot of accusations and attacks. Politifact trying to separate the fact from fiction.
The race between Republican Ron Johnson and Democrat Russ Feingold for Senate is expected to be a fierce fight in the fall.
Medicare will likely be a big issue and the state Democratic party is already trying to use it against Johnson.
"What the party says is Ron Johnson voted to change Medicare into a voucher program," said Tom Kertscher with the Milwaukee Journal Sentinel.
Right now Medicare pays fees to doctors and hospitals.The plan Johnson voted for would allow the government to give people on Medicare a fixed subsidy or money to buy private health insurance to pay their medical bills.
"What Johnson voted for never became law, it was part of a federal budget plan that Paul Ryan put forward," said Kertscher.
In fact, in 2001 Democrats claimed Republicans voting for Ryan's budget "voted to end Medicare." Nationally, Politifact called that the Lie of the Year. But did Johnson vote to turn Medicare into a voucher programs as state Democrats claimed.
Politfact rated this claim Mostly True.
"The only wrinkle here is that Republicans prefer to use the term premium supports - that they would provide money to support paying your premiums for insurance," said Tom Kertscher.
