Former Navy captain and retired astronaut Mark Kelly's Democratic Senate campaign in Arizona announced Tuesday it raised nearly $12.8 million in the second quarter.
Why it matters: The massive haul means the campaign has $24 million in cash on hand heading into the final stretch of the race against incumbent Republican Sen. Martha McSally, with a continued lead in the polls. The campaign says it received an average contribution of about $44 — and 89% of donations were less than $100.
