Donald Trump exposes Jeb Bush's problem (Jonathan Allen) from Vox
"Jeb Bush planned to win the Republican primary with a shock-and-awe strategy. Instead, it's been a shocking fall for the onetime GOP frontrunner. He started the campaign with the most famous name in Republican politics, a $100 million-plus stake, and clear, if underwhelming, favorite status in early polling. But Bush has fallen fastest and farthest against the backdrop of Donald Trump's rise."
