EAGAN, Minn. We don't know who will be Mitt Romney's running mate, but both contenders reported to be on the short list are cornering the dairy market.

Tomorrow Ohio Senator Rob Portman is meeting employees at the Dannon Yogurt and Crown Equipment in New Bremen, Ohio.

On a call Thursday with reporters, Portman was asked if he would be confirming his VP candidacy at a press conference following the tour.

"The only thing I can confirm is that I will be eating yogurt," Portman said.

And the New Hampshire Republican Party - perhaps thinking more longterm, if less about calories - sent out this tweet Thursday afternoon that former Minnesota Gov. Tim Pawlenty will be at an ice cream social event in Manchester on Aug. 11.

@NHGOP Aug 11 ice cream social w/ Tim Pawlenty at 1800 Elm St Manch from 1 - 3. $20 per ticket, RSVP online here http://t.co/OcMP7VgE

A New Hampshire Republican confirmed the event and tells ABC News the ice cream social is a "state party event," but they "work closely with the Romney campaign" and they are "aware of the event."

The event is a "candidate fair" with tables for local candidates and groups. They are expecting about 200 people and there will be a VIP reception beforehand featuring Pawlenty.

When asked what will happen to the event if Pawlenty is chosen as Mitt Romney's running mate, he answered, "We'll make more money."

There will also be a lot more press.
