Bloomie is a traditional Republican (think Bush, Reagan, Eisenhower) on issues such a free trade, immigration, foreign policy and national defense. Unlike the other Democrats who are at least paying lip service to the “woke” (radical socialist, somewhat bolshevik, agenda), he would appeal to many of the “Country Club” (“Wall Street”) Republicans and the NeoCons, who can’t stand Trump but are terrified of what the Democrats are offereing (e.g. Trump may be an isolationist, but most Democrats are surrender monkeys, Trump is undermining world trade but the Democrats will destroy the American economy, Trump may be making a mockery of the Constitution but the Democrats threaten to tear it up). Remember that Bloomie is running against a Democrat field that has apparently turned Marxist (though occasionally they get confused and follow Groucho rather than Karl).
If you love Trump, Bloomie is your biggest threat. If you hate Trump, Bloomie is your best hope.
