WASHINGTON (Reuters) - Democratic U.S. Senate candidate Mark Kelly's lead over Arizona Republican incumbent Martha McSally is holding steady with less than a week to go until an election 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 next Tuesday's 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.
