This week … Chris McDaniel launched another Senate primary run in Mississippi, voters picked their candidates in Arizona, and underdog Democrats used the gun debate to make their mark.
Decision Time in the Desert: Former state Sen. Debbie Lesko won the GOP primary Tuesday in the special election to replace GOP Rep. Trent Franks (who resigned amid sexual harassment allegations). She’s in a strong position heading into the April 24 special election, since President Donald Trump carried the seat by 21 points. Lesko will face emergency room physician Hiral Tipirneni, whom Democrats see as a strong candidate. So Lesko might not want to get too confident. Nathan Gonzales shifted this race rating from Solid Republican to Likely Republican, because, well, special elections have been pretty crazy this cycle.
