Former Vice President Joe Biden won the democratic primaries in Wisconsin.
According to official results, he won 63 percent of the vote, while Vermont Senator Bernie Sanders won 32 percent.
However, the victory of the former Vice-President lost its real meaning after Sanders left the race a day after the vote in Wisconsin on 7 April.
Sanders supported Biden on Monday.
Meanwhile, Democrat-backed District Court Judge Jill Karofsky won a tense battle for a seat on the Wisconsin Supreme Court by replacing incumbent Judge Daniel Kelly, supported by President Donald Trump.
