The fight for control of the U.S. Senate is down to seats in five states, four of which are currently occupied by Democrats. Roll Call,
“Republicans must win only two of those contests to guarantee the 51 seats they need to control the Senate for the last two years of Barack Obama’s presidency. And they need to win only one of the Democratic states if they hold the only GOP seat at serious risk.
“While things could still change — and national polls continue to show an environment that may produce a substantial GOP wave in the House and Senate — the Senate battle has boiled down to two reliably red states and three swing states.
“While you can find Democrats spinning a yarn about how their party could pull off an upset in a multi-candidate race in South Dakota, that state, plus West Virginia and Montana, look poised to flip to the GOP in November.”
