On many levels, this line of attack is absurd.
Obama’s Republican predecessor oversaw big increases in public-health sector spending, and both Democrats and Republicans in recent years have broadly supported efforts to rein in federal spending. Sequestration resulted from a bipartisan agreement. In some years, Congress has allocated more money for NIH and CDC than the Obama administration requested. Meanwhile, contrary to the suggestion of the DCCC ad, there never was a specific vote on funding to prevent Ebola.
There’s no doubt that spending has been cut, or at least failed to keep pace with inflation, but the fingerprints of both parties are on the knives. This blame game earns Four Pinocchios.
