John Kasich's presidential campaign increased its attacks on Donald Trump ahead of Trump's visit to Ohio.

The governor's campaign rounded up other Ohio politicos — Congressman Pat Tiberi, State Senate President Keith Faber, and State Sen. Peggy Lehner — for a conference call with reporters to "discuss Donald Trump." The Buckeye State officials chose instead to focus on Kasich and reluctantly mentioned Trump by name, choosing instead to express dismay about Trump's lack of governmental experience and his remarks about a database of Muslim Americans.

But the Kasich campaign has not minced words. It released a new ad with a tag line, "Does Donald Trump even know what he's talking about?" The campaign wove together together clips of Trump commenting on the hypothetical creation of a registry of Muslim Americans.
