Former South Bend Mayor Pete Buttigieg is expected to suspend his 2020 presidential campaign, a campaign aide tells NBC News.

His fourth-place finish in South Carolina exposed a core vulnerability, namely the inability to attract the support of black voters who are vital to any winning Democratic coalition.

Now he heads into Super Tuesday without momentum and scrambling for money against other moderate candidates who have both.

Even some Democrats who are among his admirers are saying that it may be time to consider whether it’s wise to go much farther.
