On April 25, the Federal Election Commission updated its useful chart of 2022 congressional primary dates, and filing deadlines. See it here.
Ironically, the new version is already out-of-date; the New York primary for U.S. House was shifted to August 23, since the chart was published. Thanks to Thomas Jones for the link.
Thanks Richard. It’s nice to see my state (CT) have reasonable dates & deadlines, compared to some of the others, which are super early! I mean, some filing deadlines (including for independents who have no primary) have passed already!
