Sorry but it is just not that simple. The world isn't always black and white. For Jeb and Floridians that is probably true as Florida is a toss-up. For those in solid red or blue states, their non-vote makes no difference.
If someone doesn't like Trump, then don't vote for him but for God's sake don't vote for Clinton who stands for everything that conservatives/Republicans detest. At least, Jeb got that right although it wouldn't surprise me when the curtain closes behind him in the voting booth that Jeb votes for Hillary.
No it IS that simple:
As Dennis Miller put it:
“Don’t kid yourself. At this point, any vote for anyone that is not Donald Trump is a vote for Hillary Clinton. Also, both Presidential boxes left blank is a vote for Hillary Clinton because as mindless as Liberals can be even they don’t enter into suicide pacts with that petulant, whiny part of themselves. As that is your wont, fine...do it! But don’t bullshit yourself. You’re electing Hillary Clinton because you want to elect Hillary Clinton.” Dennis Miller
