(CNN) There's every reason to believe former Vice President Joe Biden will be the Democratic nominee outside of some statistically improbable event. Candidates in Biden's position have always gone on to win the Democratic Party's nomination. Since 1988, the candidate with a delegate lead following the round of contests after Super Tuesday has taken the Democratic nomination six of six times in competitive primaries. Some of those were close calls (see Michael Dukakis in 1988), but there's no reason to believe this will be one of those situations. Once a candidate jumps out to a clear lead with a substantial number of delegates allotted, as Biden has, an opponent must start winning contests by large margins.
