The Republican challenger to Rep. Kerry Bentivolio, R-Mich., is on the air with a positive spot and is putting big money behind it.  

Attorney David Trott’s campaign aired a spot featuring him commuting to work and touts him as a job creator and Washington outsider. A spokeswoman said the campaign’s ad buy was well into the six figures.
