WASHINGTON (Reuters) – Democratic U.S. Senate candidate Mark Kelly’s lead over Arizona Republican incumbent Martha McSally appeared to narrow in a race that could determine whether Republicans lose control of the Senate, a Reuters/Ipsos poll showed on Wednesday.
There are about 12 competitive U.S. Senate races up for grabs in the Nov. 3 election, 10 with vulnerable Republican incumbents and two with vulnerable Democrats. To have a majority in the Senate, Democrats need to pick up three seats if the party wins the White House, which gives the vice president a tie-breaking vote, and four if not.
Here are the latest results for three Senate races on which Reuters/Ipsos is polling:
ARIZONA (Oct. 14-21 poll)
* Voting for Democratic challenger and former astronaut Mark Kelly: 51%
* Voting for Republican Senator Martha McSally: 44%
* Kelly was up 52%-41% in the prior poll.
* 27% said they had already voted.
NORTH CAROLINA (Oct. 14-20 poll)
* Voting for Democratic challenger Cal Cunningham: 47%
* Voting for Republican Senator Thom Tillis: 47%
* Cunningham led Tillis 46%-42% in the prior week.
* 12% said they had already voted.
MICHIGAN (Oct. 14-20 poll)
* Voting for Democratic Senator Gary Peters: 50%
* Voting for Republican challenger John James: 45%
* Peters led James 52%-44% in the prior week.
* 28% said they had already voted.
NOTES: The Reuters/Ipsos poll was conducted online and in English. The Arizona survey included 658 likely voters and had a credibility interval of 4 percentage points. The earlier Michigan poll surveyed 686 likely voters and had a credibility interval of 4 percentage points. North Carolina’s surveyed 660 likely voters and had a credibility interval of 4 percentage points.
