LOL, and Trump himself has shifted a bit...

Trump’s political flip-flopping over the past quarter-century is best chronicled in the files of New York City’s Board of Elections, where the businessman’s assorted voter registration cards are stored. Here’s what they reveal:
* In July 1987, Trump first registered from his penthouse in Manhattan’s Trump Tower. He enrolled in the REPUBLICAN PARTY, listing his prior residence as his boyhood home in Jamaica Estates, Queens.
* Twelve years later, in October 1999, Trump dumped the GOP, and enrolled in the INDEPENDENCE PARTY.
* Less than two years later, in August 2001, Trump again changed his party enrollment. This time, he emerged as a member of the DEMOCRATIC PARTY.
* He lasted eight years as a Democrat. In September 2009, Trump changed his affiliation, this time returning to the REPUBLICAN PARTY.
* As of press time, Trump’s latest party switch occurred six weeks ago, on December 21, when he again ditched the GOP. But instead of siding with a particular party, Trump checked off the box indicating “I DO NOT WISH TO ENROLL IN A PARTY.”
