There are plenty of people in this country that are of sound mind and have no checkered past who could run for president — but in the current political climate in Washington no one of sound mind would want to run for president.
I forget who said it nor can I quote them exactly, but it went something like...
"Any man capable of getting themselves elected president is unfit for the position"
(I thought it might have been a Mark Twain?)
That does seem to be the general trend for major political offices as of late. "Nice guys always finish last" seems to ring the truest in political races.
