. . . or why you should ignore most pundits. From Vox last July:
Donald Trump’s surge in the polls has been covered as terrible news for the GOP. But it’s fantastic news for one Republican — Jeb Bush.
The rise of the bombastic celebrity mogul and the saturation media coverage of his controversial comments on illegal immigrants is a godsend for the putative frontrunner, who, in every area except fundraising, has been underperforming so far.
In addition to the fact that Trump poses no threat to actually win the Republican nomination, the purported billionaire helpfully sucks up all the media oxygen so none of Bush’s potentially more dangerous rivals can get any attention. Trump also presents a wonderful contrast for Bush — making him look tolerant, professional, and adult. And if Trump stays in the race and remains popular on the right, it will show that yet again, conservative voters simply can’t get it together to seriously wield their influence in the presidential primaries.
