Are you sure this is satire?

Scrappleface satirically has le Sénateur Kerry protesting Republican Massachusetts Governor Mitt Romney's suggestion that, having missed nearly 90% of Senate votes this year, the presumptive Democratic Presidential nominee might want to consider resigning from that body. Monsieur Kerry is quoted as arguing that he is just as effective a senator when he's not doing his job as when he is- a very admissible argument, it seems to me.
