Looking for a movie probably about 15 years old. It was about a man running for president saying his heritage was irish and he sent his pr ( a short dark haired girl ) to Ireland to get things ready for his visit and to find his relatives. It was all a sham, she fell in love and stayed in Ireland...
It wasn't Minnie Driver but looked like her

The MatchMaker (http://www.imdb.com/title/tt0119632/)

You are awesome; this took about 3 minutes and I have been wracking my brain for about 3 years :) THANK YOU! Can't wait to watch it.

Glad to help :)
