Voters in Pensylvannia's Democratic primary election are letting their taste buds do the talking.

Philapelphia sandwich shop Di Bruno Bros. has pitted the Obama bratwurst up against the Hillary Big City sandwich.

The Obama features bratwurst topped with a speciality the Senator himself makes - Kobe beef chile and cheese.

The Hillary Big City is a New York special with lots of extra pizzaz - pastrami on rye with olive tapenade, pickled tomatoes, onions, mustard and Emmenthaler cheese.

Food Service Manager Dan Ferraiolo: "Both sandwiches just took off really well for us here at Di Bruno Bros.

"They're actually neck and neck right now, 371 - 369, so it's always been every day kind of neck and neck who's going on top."
