What are the 10 key Senate battleground states?

To secure control of the Senate, Democrats must retain all the seats they currently hold and win at least four additional seats from Republicans. Although the task remains challenging, polling suggests Democrats have a realistic opportunity to gain ground in several Republican-held states.

Here are 10 battleground states where Democrats could potentially flip Republican-held Senate seats, :Georgia:Democrat Jon Ossoff is polling at 52 percent against Republican Mike Collins at 42 percent. Opinion polls suggest Georgia is likely to flip to the Democrats.

Texas:Democrat James Talarico is leading polls at about 49 percent against Ken Paxton’s 46 percent. A different poll gives Talarico 50 percent, while Paxton is at 43 percent. This race is close, but polling suggests Talarico is poised to turn Texas blue for the first time since 1993.

Iowa:Democrat Josh Turek is polling at 48 percent, slightly ahead of Republican Ashley Hinson at 47 percent. Iowa is considered a swing state, but voted for Trump in the last three presidential elections. Kansas:Democrat Adam Hamilton is currently at 49 percent, while Republican Roger Marshall is at 44 percent.

Kansas hasn’t elected a Democratic senator since 1932, so for this state to flip would be monumental. Maine:Democrat Troy Jackson is at 51 percent, while his Republican opponent Susan Collins is at 45 percent. If Jackson wins, it would mean Collins leaving the Senate nearly 30 years after winning her seat in 1997.

New Hampshire:Democrat Chris Pappas is on 54 percent, while Republican John Sununu is on 41 percent. Pappas looks likely to take the state, and has been expanding his lead in recent polling. Michigan:One poll puts Democrat Abdul El-Sayed at 53 percent, while Republican Mike Rogers is at 42 percent.

Another is closer, with El-Sayed on 48 percent and Rogers on 46 percent. This close race has drawn a lot of attention, in part because El-Sayed’s Democratic opposition in the primaries backed Rogers days before the vote.

Ohio:Democrat Sherrod Brown is on 49 percent in one poll, and 45 percent in another, while Republican Jon Husted is at 44 percent in both. Ohio is traditionally one of the most hard-fought states in the US, and this year’s race is no different.

North Carolina:Democrat Roy Cooper is on 55 percent in one poll and 54 percent in another, against Republican Michael Whatley’s 45 percent and 44 percent, respectively. This is among the states most likely to flip to the Democrats.

Alaska:Democrat Mary Peltola and Republican Dan S Sullivan are currently sitting at 50 percent each. This very tight race has been marred by accusations that Democrats have tried to manipulate the outcome.
