Most Read from BloombergSpeaking at a picnic in rural northwestern Iowa, the as-yet-undeclared candidate for president again avoided mentioning former President Donald Trump by name. He’s been holding private dinners in recent weeks to persuade donors he’s a drama-free alternative to Trump. Iowa will be a critical test of whether any of Trump’s challengers can overcome the former president’s popularity with Republican voters. A new poll of 500 likely Republican Iowa caucus voters released Friday showed Trump with an 18-point lead over DeSantis, 44% to 26%. DeSantis picked up 37 endorsements from state legislative leaders in Iowa on Friday, including Senate President Amy Sinclair and House Majority Leader Matt Windschitl.
