Gwen Graham is using her first digital ad to call out Donald Trump.

The former congresswoman and Democratic candidate for governor called President Trump "an example of a bully" in a newly released 45-second digital ad Tuesday.

"We have a president that could not be more ill-suited to be president of the United States of America," Graham says in the spot.

The ad is set to run for a month on Facebook, Twitter and YouTube, campaign spokesman Matt Harringer said. The campaign invested significantly in the buy, Harringer said, but he did not offer specifics.

"I hope Trump sees this ad during one of the many occasions he is checking Twitter," Graham said in a Tuesday release touting the ad.

In a cycle that may turn out to be a referendum of sorts on the headline-grabbing president, bashing Trump is a safe bet for any Democrat. Graham's opponents for the Democratic nomination, Chris King, Philip Levine and Andrew Gillum, routinely call out the Trump for his conservative policies and brash statements. (In December, Gillum even called for Trump's impeachment.)

The release of the ad comes at a time when some polling shows  Graham struggling to seize control of the Democratic race. But the same polling shows that most voters have yet to tune into the campaign for governor.
