The Republican elite are STILL delusional in spite of Jeb's lack of support. Bloomberg will only attract the puppetmasters who would've voted for hillary. Meanwhile, the seething anger will put a whole lot of new, angry and/or not politically affiliated voters into Trump's column.
The only other possible result of a Bloomberg candidacy would be to annihilate the Republican Party.
Are you assuming he's running as a republican and not an independent or democrat?
