Donald Trump made history Thursday night by accepting the Republican Party's nomination for president, a feat that a year ago very few imagined. And on Friday morning, he made headlines by attacking … Ted Cruz? Wait a second. Aren't the primaries over? They are, but Trump — like Cruz — has shown an incredible stubbornness to let go of grudges; this one in particular. Trump spoke to Republican National Committee volunteers on Friday morning in Cleveland, where he spent a significant amount of time insulting Cruz after the GOP runner-up gave a convention speech in which he refused to endorse Trump and later said he wouldn't because Trump had attacked his family. (Their feud goes back further than this week, but this newsletter is supposed to take only five minutes to read!) In a separate interview with CBS's Ted Koppel, Trump called the fact Cruz got booed during his convention speech "beautiful." Besides being unable to let go of a grudge, we're not that clear on why Trump is doing this. Cruz isn't a threat to Trump anymore. (At least, not until 2020, if the stars line up right.) And this is not the message Republicans want him to focus on. They want him to talk almost exclusively about Hillary Clinton and her perceived faults. That's because polls suggest the presidential race could be tight and decided by which candidate people dislike less. But the day after accepting the nomination, all Trump can talk about — and all the media can write about — is his feud with Cruz. This should be a red flag for Republicans who had hoped that the past four days of pageantry and speeches and balloon drops and fireworks would have somehow turned Trump into a more traditional politician, like fairy dust sprinkling over and magically transforming a Disney character.

For Trump, being seen isn't necessarily a bad thing As The Fix's Aaron Blake writes, Trump wants you to love him, but mostly he wants you to pay attention to him. Trump's tweet earlier in the week about his wife's plagiarism scandal sums up his philosophy nicely: Blake: "Trump might not believe that all press is good press, but he clearly thinks the vast majority of it is. He thinks this because it worked for him in the GOP primary. He used invective, false claims and extreme policy proposals that other Republicans wouldn't touch to gobble up media attention. His opponents raised tens of millions of dollars but could never penetrate with their messages because he made news just about every single day and was such a bigger story. |
