Washington Post: “Rival campaigns have also begun to raise concerns about whether Bloomberg’s strength could help speed Sanders’s path to the nomination by further splitting the moderate vote in the party. Under Democratic rules, candidates can only accrue delegates if they clear 15 percent support thresholds, which are measured on both statewide and congressional district levels.”
“Bloomberg’s aides, who privately share the same concern about the moderate vote splitting in a way that helps Sanders, said the burden is on other candidates ‘to get out’ if they have failed to perform in the early contests.”
“Behind the scenes, Bloomberg, who is worth more than $50 billion, has stepped up his debate preparations, which began last year, as he faces what is likely to be the next major test of his campaign.”
