It's the same commercial slogan for the anti-depressant, Effexor.

" Due to the pronounced side effects and suspicions that venlafaxine may significantly increase the risk of suicide, it is not recommended as a first line treatment of depression. However, it is often effective for depression not responding to SSRIs. Venlafaxine was the sixth most widely-used antidepressant based on the number of retail prescriptions in the US (17.1 million) in 2006.[1]"  

If you voted for bush, twice!  Wouldn't a drug that might cause suicide be kind of comforting?  Thus the excellent GOP sloganeering!  

"Change you deserve"?  Death by your own hand.  Better than living through a bush-lite (mccain) administration.  Why not?

And don't try to quit Effexor, it will get you.  Oh yes.  As bad as  trying to quit the GOP?  Worse, much much worse.
