Republicans are challenging extended mail ballot deadlines in at least two states in a move that could have severe implications for mail voting nationwide ahead of this year's presidential election. A lawsuit filed last week in Mississippi follows a similar one last year in North Dakota, both brought in heavily Republican states before conservative federal courts. (AP Photo/Matt Slocum, File)
