Story highlights Clinton has stepped up attacks on Sanders in the last two week

Her new ad does not mention Sanders by name

Adel, Iowa (CNN) Hillary Clinton's campaign released an ad in Iowa comparing the former secretary of state to Sen. Bernie Sanders, subtly dinging him on health care, guns and Planned Parenthood, according to Kantar Media/CMAG.

The ad, which ran in Des Moines on Wednesday morning, questions Sanders' ability to "actually make a difference for you," while casting Clinton as the person "with the experience and determination to get the job done."

"The time has come to make a choice, about which candidate can actually make a difference for you," a narrator says.

While Clinton has stepped up the attacks on Sanders in the last two weeks, she has vacillated between knocking the Vermont senator, who is running close with Clinton in Iowa, and pushing her own platform and message.

"[Clinton] will build on Obamacare, not start over, break through the gridlock, not add to it, defend Planned Parenthood, not attack it, stand up to the gun lobby, not protect it, lead on foreign policy, not ignore it," the narrator adds in a not-so-subtle knock against the Vermont senator.
