A “Bloomberg Republican” is a Democrat who runs as a Republican because it gives him an easier path to the general election. I coined the term based on Michael Bloomberg, a lifelong Democrat who ran for Mayor of New York City as a Republican in 2001. Incumbent Mayor Rudy Giuliani was leaving due to term limits and the Republican primary offered an easier path to the general election, and ultimate victory, than entering a crowded Democrat primary field that ultimately failed to produce a winner requiring a primary runoff election. Bloomberg eventually left the Republican party, which he was never a part of philosophically, over policy differences–not surprising for a previously lifelong Democrat–and ran for reelection as an independent.
"Mr. Obama, you're fired!"
There are a lot of theories about the motives and intentions of Presidential hopeful (or noisemaker), real estate mogul, and reality TV star Donald Trump. Trump, formerly a registered Democrat, is indicating that he will run as a Republican. Theories range from relatively innocuous (a publicity stunt to promote The Apprentice) to straight-forward (frustration with Obama and Democrats) to conspiratorial (an orchestrated effort by pro-Obama forces to discredit and/or sabotage the Republican nomination process). He has stated that he will make an announcement in the Finale of The Apprentice (maybe he’ll look into the camera and say “Mr. Obama, you’re fired!”). On the other hand, there are reasons to believe he’s serious about running; he’s certainly got the ego for it. I don’t pretend to know the answer, but I’d like to toss out another theory that I find far more plausible than conspiracy theories–Donald Trump is another Bloomberg Republican. In other words, he wants to challenge Mr. Obama because he’s dissatisfied with administration, but doesn’t want to launch a primary challenge against an incumbent.
