After months of hand-wringing over how it would cover its boss, Bloomberg News ran a story questioning how 2020 Democrat Michael Bloomberg would pay for campaign spending promises.

Bloomberg News reported over the weekend that the billionaire co-founder and CEO of Bloomberg LP’s delay in putting out his tax plan was fueling uncertainty regarding how he would pay for the pitches he is making to Democrats. Since announcing his candidacy for the White House in November, Bloomberg, 77, has rolled out proposals such as $1.5 trillion healthcare and $1.2 trillion infrastructure platforms.
