Shrinking Senate Map Boosts Democrats

“The Senate battleground map has shrunk dramatically in recent weeks — a net plus for Democrats but not enough to change their status as heavy underdogs to win the chamber in November,” Politico reports.

“Democratic incumbents look increasingly safe in four Rust Belt states President Trump carried in 2016 — Ohio, Michigan, Pennsylvania and Wisconsin, where Republicans are locked in a bitter primary until August. Both parties agree a core universe of states are truly in play: Republicans are targeting Democratic incumbents in Missouri, Indiana, Florida and North Dakota, while Democrats are contesting GOP-held seats in Nevada, Arizona and Tennessee. There is disagreement on how competitive West Virginia and Montana are.”
