Before her two, main rivals got too far tagging Democratic front-runner Hillary Clinton’s commitment to reforming Social Security, Clinton unveiled an ad to innoculate herself today.

  The 30-second commercial touts her support of causes for seniors including her authorship of the Lifespan Respite Care Act that would permit up to $300 million in competitive grants over the next five years to states that expand at-home services for senior citizens and the disabled.

   The ad is being aired on TV stations in New Hampshire and Iowa.
