Primary Voting/Caucusing Begins in 3 Months

On the eve of the next candidate debate, National Journal's Josh Kraushaar does an overview of the top 4 candidates for the Democrat nomination. I like his conclusion.

Each of the leading candidates commands support from a different demographic faction. Biden is dominant with African-Americans, over-performs with working-class voters and is the clear favorite with seniors. He badly lags with younger voters.

Sanders boasts the opposite coalition: He continues to be a hit with progressive millennials and is a turnoff to older voters. He’s showing signs of strength with Hispanic voters—at least in Nevada. Unlike Buttigieg and Warren, he boasts disproportionate support from the working-class wing of the party.

Buttigieg is the favorite among college-educated moderate white suburbanites, while Warren’s base is with college-educated white liberal women.

The biggest question of all is whether momentum matters in a primary field that’s deeply divided along demographic lines.

Anybody want to wager against a brokered convention, or one in which no candidate arrives with a working majority of delegates? Kraushaar would be tempted to take that bet. The Democrats' 'tent' is so big it includes groups with divergent mind sets, something once a Republican problem.
