Robert F. Kennedy, Jr. was on the ballot in some states as the nominee of the We the People Party, but now that the election is over, his party is not ballot-qualified in any state except Oregon. In Oregon, a new party gets the next two elections.
We the People would also be qualified in Wisconsin now if Kennedy had polled as much as 1% of the presidential vote in that state, but he only got .5%. He had fought to get off the ballot in Wisconsin so it is not surprising that he didn’t get 1% there.
