Story highlights In two days, Hillary Clinton has stressed the need for 'steady hands' in reference to running the country

References to the hands of Republican front-runner Donald Trump have been a political landmine during this primary season

Seattle (CNN) For those who thought the unusual story line related to Donald Trump's hands had left the 2016 campaign trail with Sen. Marco Rubio, Hillary Clinton does not appear quite ready to let it go.

The former secretary of state has mentioned the need for "steady hands" twice in the last two days, a not-so-subtle reference to the Republican front-runner's habit of publicly defending the size of his hands.

Clinton told CNN's Wolf Blitzer on Tuesday that she had no interest in responding to Trump's "constant stream of insults," in reference to Trump's habit of taking colorful shots at his campaign opponents on the trail and on social media.

"Let me talk about what I will do, what I have done and what kind of commander and chief I will be.

The need for "steady hands" is a generally new talking point for Clinton.
