The Trump effect is now probably long-term, meaning that even if he falls by the wayside in the nomination contest, he will continue to be a factor. Maybe he will run as an independent. Maybe he will make life difficult for the eventual GOP nominee from his permanent headquarters on Twitter. Or maybe it’s simply the accumulation of his offensive statements on videotape that will be used by Democrats to taint the fall Republican ticket.
An aside: How in the world will the Republican Party ever reunify behind its nominee in time and with sufficient enthusiasm to win next November? Right now, it appears that the party must depend on its members’ deep-seated, intense antipathy toward Barack Obama and Hillary Clinton to do the trick — neither of whom, it should be emphasized, are all that popular with the general electorate at the moment. In addition, the international situation, coupled with domestic terrorism, may be the extra fuel needed for the GOP to prevail. Finally, in a partisan age, we should expect Republican voters to rally around the party in the general election, although a divisive nominee will test this expectation. All of this will be revisited another day, when the smoke of the nomination fight finally starts to clear.
