Online petitions for Democratic candidates

An individual in Fairfax County has established a website that enables Democratic voters to sign petitions for prospective Democratic candidates for the June 2021 primary election online.
This is the website:
You will be asked for your name, address and last four digits of your Social Security number — the SSAN last four is mandatory.  You then will be asked to select your locality — there is a drop-down menu, scroll down to Northumberland County (or your county if not Northumberland).
You will see a list of Democratic candidates for Governor, Lt Governor, and Attorney General as well as candidates for House of Delegates, if any.  Rev. Linwood Blizzard’s name is available for voters in the 99th District.  Check the box beside the candidates whose petitions you want to sign and scroll down to click on SUBMIT.
