I know... it is often hard to get inspired by the choices, as the actions blur-- but I was taught this in High School & it has been a useful philosophy-- Vote against the candidate you think will do the most harm.
I have had to *hold my nose* to vote-- voting against the worst of the choices.

 Not voting, is akin to voting for the worst candidate. 

People fought long & hard to have the right to vote, lets honor them & keep the worst of the lot out of office.
