On Friday morning, Donald Trump made his first public appearance after the end of the Republican National Convention, which offered him an opportunity to look ahead to the general election. Instead, the Republican nominee seemed eager to re-litigate the GOP primaries -- including Trump's ongoing interest in Ted Cruz's father and a JFK assassination conspiracy theory.
It was a striking reminder: Trump may be eager to take on Hillary Clinton in the general election, but the Republican candidate isn't quite done thinking about his intra-party rivals.
The question, however, is just how far down this road Trump intends to go. A prominent Trump ally suggested last Thursday, for example, that the GOP nominee may support a primary challenger to take on Ted Cruz in Texas in 2018.
Trump himself made a similar comment on Friday -- after talking about Cruz's father and Lee Harvey Oswald -- saying in reference to the Texas senator, "Maybe I'll set up a super PAC if he decides to run." Turning to his running mate, Indiana Gov. Mike Pence, Trump added, "Are you allowed to set up a super-PAC, Mike, if you are the president, to fight somebody?"
By late Friday, sources close to Trump were saying Trump intends to "create and fund super-PACs specifically aimed at ending the political careers of Ted Cruz and John Kasich should either run for office again." On "Meet the Press" yesterday, the Republican nominee confirmed those plans to NBC's Chuck Todd.
"Look, what's on my mind is beating Hillary Clinton. What's on my mind is winning for the Republican Party. With that being said, yeah, I'll probably do a super PAC, you know, when they run against Kasich, for $10 million to $20 million, against Ted Cruz. And maybe one other person that I'm thinking about."
Asked who the other Republican might be, Trump told the host, "I won't tell you that."
All of this should be quite alarming for GOP officials for a variety of reasons, some more obvious than others.
