this is the link i found, it has B-50 K-44 among likely voters! good news it appears!
50-44 matches yesterdays poll. They said 'new Newsweek poll'. They had other new polls from today up when they said this but didn't have NW up. Maybe didn't change from yesterday. I don't know. Just saying what they said...'new'
