The GOP has 18 cards. One is sure to please your Valentine.
Some options:

Barack Obama (Gee, thanks - FOR NOTHING!)

Hillary Clinton (She's sleazier than Menendez and her husband combined.)

Joe Biden (Joey is a champion speller!)

Dianne Feinstein (Happily eroding our rights.)

Nancy Pelosi (We have a Leftist problem.)

Barack Obama (You can't buy love, but you can buy dependency.)
