If Democrats are going to have a realistic shot of winning the Senate, they will have to win the races in two of the states with primaries on Tuesday: Arizona and Florida. If they lose either one, their chance to win the Senate goes down precipitously.
Democrats have an uphill battle to take back the Senate in November. They need a net pickup of two seats, and only nine of the 35 seats up for election in 2018 are currently held by Republicans. Ten of the Democrats (or independents who caucus with the Democrats) occupy seats in states President Donald Trump won in 2016. CONT.
