AFP: Astronaut Mark Kelly is leading an unlikely political “mission” to win a second Senate seat for the Democrats in the traditionally conservative state of Arizona.
 Until recently, few would have thought it possible for the Democratic Party to make major inroads in this southwestern state with a long Republican tradition.
 But thanks to changing demographics and growing discontent with President Donald Trump among the state’s moderate conservatives, Kelly believes he can win the upper-house seat while helping deliver Arizona’s electoral college votes for Joe Biden.
 Kelly, who served 25 years in the US Navy and with NASA, is drawing significant attention not just for his background and the boost he could give Biden’s presidential bid, but because victory would give Arizona two Democratic senators for the first time in six decades.
“Mark Kelly has a really good shot at winning the seat,” said Arizona State University politics lecturer Gina Woodall.
