So your scenario is not plausible.

Then you have nothing to worry about. But I think you are wrong. I think Bloomberg would have a much better chance to win in states like NY, NJ, etc. He could run as a "moderate" progressive, painting Trump as a racist demagogue and painting Hillary/Bernie as socialists. Most NE Republicans tend to be more liberal and would oppose Trump in immigration; independents and Dems in those states that do not want to vote for Hillary might vote for Trump is there is not an alternative, but Bloomberg would give them that alternative.

Anyone on the Republican side who likes Bloomberg would vote for Trump and anyone on the Dem side who likes him would vote for Hillary or Sanders first. He brings nothing to the table for anyone in the northeast. And he is despised everywhere else (among people who have even heard of him).

Trump, on the other hand, attracts some Democrats in the Northeast, and doesn't repel any Republicans, except the country clubbers/Wall Street types.

I didn't say I was worried. I think Bloomberg, at best, would siphon off maybe 5-10 percent of the vote, and more would come from the Dem nominee than the Republican.
