Who are Bernie fans going to vote for if Hillary gets the nomination? Hillary!
The secret to Democrat wins is they consistently unite behind the nominee.
Who are Cruz fans going to vote for if Trump gets the Republican nomination? Nobody!
Who are Trump fans going to vote for if Cruz gets the nomination? Nobody!
Who are Rand Paul fans going to vote for since he didn't get the Republican nomination? The same as with his father 4 years ago -- nobody!
Many Republicans myopically withhold their votes because their favorite isn't the nominee and forfeit the advantage that Conservatives outnumber Liberals as much as two to one.
That, folks, is how we got Bill Clinton -- twice. That is how we got Obama -- twice. That is how we got Ruth Bader Ginsburg, Stephen Breyer, Sonia Sotomayor, and Elena Kagan.
The fools who stay home (or vote for a third-party candidate with absolutely no chance of winning) simply because their favorite isn't in the race are harming us all. The same goes for the fools who don't vote because they think their votes don't matter. (They're right -- votes don't matter if they don't exist.)
The argument against voting for the lesser of two evils (ie the person who do the least damage to the Constitution) presumes that there is a perfect alternative. The reason evil wins is the refusal to vote if perfection isn't on the ballot.
Remember this: We crucified the last person who was perfect. There will be no perfect person on the ballot in this year's primary election or in the general election. Your best choice is to vote for the candidate you think will do the least damage to the Constitution. Anything else gives the rest of us the person you know darned well will do the most damage.
They won't say it, but Democrats thank you.
