Amid ongoing questions over Hillary Clinton’s health status, another Democrat is attempting to reassure voters that her running mate, Tim Kaine, is ready to be president.

“I can tell you Tim Kaine is prepared to be the president of the United States,” former Sen. Bob Graham told an audience in Miami on Sunday.

Graham is the second high-level Democrat to shore up support through Kaine.

During a rally in Ohio less than two weeks ago, Senate candidate Ted Strickland told the audience Kaine is “ready to become the president,” according to Columbus Dispatch editor Darrel Rowland.

From the Dispatch:

Hillary Clinton should recover enough from her pneumonia to rejoin the campaign trail soon, running mate Tim Kaine said Monday in Ohio.

But ongoing concerns over the Democratic presidential candidate’s health and credibility were underscored in a seeming throwaway remark by former Ohio Gov. Ted Strickland, who said Kaine is “a wonderfully prepared person to be vice president, and to be the president if that ever became necessary.” The comment went viral after it was tweeted by The Dispatch and even becoming the lead story on the Drudge Report.
