Yesterday's Democratic primary debate was the last shot for former Texas congressman, Beto O'Rourke.
While O'Rourke has made headlines in recent months over gun control.
Business Insider polling shows a steady, consistent decline in support for the candidate.
Three months before his presidential run, he was considered satisfactory by 58% of Democrats.
By the time he announced his presidential run in March, that number had dropped to 47%.
Less than 20% of Democratic voters believe he can beat Donald Trump in a general election.
He had a moment in the debate everyone is talking about.
However, it's for all the wrong reasons.
O'Rourke was pummeled by Mayor Pete Buttigieg, who slammed his gun buy-back policy.
Buttigieg, a war veteran, chastised O'Rourke and told him "I don't need you to teach me about courage."
