What makes a Republican vote against the budget?

Why did the dissenting 15 jump ship and vote against the GOP budget? It seems like Charlie Bass, Mike Castle, and Virgil Goode did it because of ANWR. Sherwood Boehlert may have cast his "nea" vote on behalf of NASA, or it could have been Medicaid, or family farms. Mark Green, who has announced that he is running for Governor of Wisconsin, may have cast his vote to prevent increasing his state's Medicaid bill. And it goes on like that.

If any readers can find a Republican who said "I'm voting 'no' on this budget because it increases the deficit with irresponsible tax cuts" please pass along a note.
