WASHINGTON (Reuters) - Democratic U.S. Senate challenger Cal Cunningham appears to lead Republican Senator Thom Tillis in North Carolina, while Democratic Senator Gary Peters of Michigan is ahead of his Republican challenger, businessman John James, a Reuters/Ipsos poll showed on Tuesday.
There are about 10 competitive U.S. Senate races this year, eight 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.
