"Dear Democrats, Doesn't Clinton Embarrass You?"

Donald Trump wears his character flaws on his sleeve. Hillary Clinton seeks to prevent documentation of hers, even when the law requires it. Yet despite her best efforts, facts about Mrs. Clinton that are now public should trouble voters more than any of Mr. Trump’s remarks.

Not that it’s easy for Republicans to appear on a ballot with Mr. Trump, especially since media folk spend days after each controversial remark demanding responses from other GOP candidates. The objective is to force them to endorse or condemn Mr. Trump and suffer the consequences.

Fair enough, but reporters don’t force down-ballot Democrats to take a position on each new Clinton email revelation. The result is wall-to-wall media coverage focused on whether GOP voters can possibly support their candidate. But why should Republicans have all the fun? Democratic voters have every right to be ashamed of their nominee.

We’ll review some of the reasons in a moment, but first let’s consider the importance of party loyalty in this year’s presidential election. In recent polls, Mr. Trump often leads among independents. But he generally trails overall because Mrs. Clinton enjoys stronger support among Democrats than Mr. Trump does among Republicans—or because pollsters don’t believe Republicans will turn out and therefore include many more Democrats than Republicans in their survey samples.

Clearly Mr. Trump needs more Republicans to support him. This could happen if holdout Republicans break his way or if some Democrats decide they can’t stomach another era of Clinton scandals.
