The article that sparked Dean’s threat asserts that President Obama’s budget will “rescue the Pentagon”:
Although the White House doesn’t advertise this fact in the six-page budget overview it put out this morning, the new budget eliminates nearly all of the cuts that sequestration imposes on the Pentagon. Instead of $500 billion in cuts, Obama proposes only $100 billion, and you have to look closely to spot it (“$200 billion in additional discretionary savings, with equal amounts from defense and nondefense programs”).
Poor spelling aside, Dean’s tweet is significant. Just four years ago, Dean was chairman of the Democratic National Committee.
