I completely do not understand the "straw man" reference.

Cassidy was a prominent voice in the discussion over healthcare, and pandered to Kimmel's very sympathetic audience, as well as, it now seems, exploited Kimmel's genuine suffering, anguish/fear and conscience over what had happened to his (Kimmel's newborn child).

Cassidy went on national TV spouting all kinds of positions, proomising that HIS approach would not only addres a child like that of Kimmel, but all children.

THEN, Cassidy CO-SPONSORS/CO-INTRODUCES, then advocates for, a bill that simply does not do what he promised.

No straw man.  KEY man.  NON-CREDIBLE man.  And clearly, not a man of integrity or principle.

Do what Cassidy did (exploit and lie), and you get it from those you exploit and lie to.

SO, Cassidy is STUPID man.  He did it to a guy with LOTS and LOTS of people watching him every weeknight.
