WASHINGTON —Representative Justin Amash does not believe the government should subsidize public broadcasting, vehemently opposes abortion rights and thinks Democrats are wrong about spending. Yet he has voted against every Republican measure that conforms to those views.

Through Tuesday, Mr. Amash (pronounced uh-MOSH), a Republican who represents a portion of southwestern Michigan, has not voted with the majority 25 percent of the time, the most of any House Republican.

Mr. Amash, 30, a lawyer and the youngest member of the freshman class, stands out even in the patchwork quilt of the 86 often-colorful Republican freshmen. He has voted against his party on important symbolic measures, like one that would strip financing from Planned Parenthood, and those most minor, like a measure to amend the Ronald Reagan Centennial Commission Act to extend its termination date.

He has even voted against the routine matter of approving the journal of the previous day’s proceedings, because, he says, there is not enough time to read it. (This is a bit like not clicking “I Agree” on a hotel Wi-Fi agreement because you don’t have time to read the fine print.)
