I really like "No more lesser evils"
I like that a lot.
How about:
"Yes it is our country, and we're taking it back."
or
It's "For the People" not "Over the People" (or "On the People")
or
Because he speaks the Truth.
Ron Paul
or
We can handle the Truth
Ron Paul for President
or
The only doctor who still makes House calls...
Dr. Ron Paul for President
or
(Iowa's state motto is "Our Liberties We Prize, and Our Rights We will Maintain")
Prize your Liberties
Maintain your Rights
Vote Ron Paul.

Wouldn't it be nice to have a First Lady who knew how to make really great potato salad and fruity jello?

(sorry about that last one, but wouldn't it be nice to have a real down to earth grandmotherly type First Lady in the White House.)
Here's Iowa's State song. It's really beautiful.
Iowa State Song
Written by S.H.M. Byers
To the music of Tannenbaum
You asked what land I love the best, Iowa, tis Iowa,
The fairest State of all the west, Iowa, O! Iowa,
From yonder Misissippi's stream
To where Missouri's waters gleam
O! fair it is as poet's dream, Iowa, in Iowa.
See yonders fields of tasseled corn, Iowa in Iowa,
Where plenty fills her golden horn, Iowa in Iowa,
See how her wonderous praries shine.
To yonder sunset’s purpling line,
O! happy land, O! land of mine, Iowa, O! Iowa.
And she has maids whose laughing eyes, Iowa, O! Iowa.
To him whose loves were Paradise, Iowa, O! Iowa
O! happiest fate that e’er was known.
Such eyes to shine for one alone,
To call such beauty all his own. Iowa, O! Iowa
Go read the story of thy past. Iowa, O! Iowa
What glorious deeds, what fame thou hast! Iowa, O! Iowa
So long as time’s great cycle runs,
Or nations weep their fallen ones,
Thou’lt not forget thy patriot sons, Iowa, O! Iowa
