I think it's nine states plus the District that send out unsolicited ballots, but you're right - - five states have been doing this for some time with no issues.Thats weird because the stats in the Tweet are for those states that do just that - send ballots to registered voters. Further only 3 states and DC have moved to this system for this election. Five states have been doing this for some time. So you really have nothing to worry about.
- Eight states, in addition to Washington, DC, will be conducting a primarily vote-by-mail election in November (CA*, CO, DC*, HI, NV*, OR, UT, VT*, WA)
- 34 states allow voters to request a mail ballots with no excuse (AL*, AK, AR*, AZ, CT*, DE*, FL, GA, ID, IL*, IA*, KS, ME, MA*, MD, MI*, MN, MO*, MT, NE, NH*, NJ, NM, NC, ND, OH*, OK, PA, RI, SD, VA, WV*, WI, WY)
- Eight states require an excuse to cast a ballot by mail (IN, KY, LA, MS, NY, SC, TN*, TX)
Also, of these nine states, most are already solidly blue and only one (Nevada) is a swing state but with just six electoral votes, so this is much ado about nothing. But Trump loves the issue because his supporters, unaware of these details, eat it up and it's additional nonsense that will support his bullshit post-election claim that the election was rigged.
