An online dictionary defines lackluster as lacking in vitality, force, or conviction; uninspired or uninspiring. Certainly sounds like the GOP presidential candidates, beginning with 17 and now down to 3.

Lackluster buster
You said it
How can they
With a straight face
Expect the voters
To elect one of them
To the highest office
In the land?
Trust one of them
With my life
And the lives
Of my children?
