“Donald Trump’s campaign is increasingly falling into disarray as the Manhattan billionaire braces for a loss in Wisconsin that could set him on course for an uncertain convention floor fight for the Republican presidential nomination,” Politico reports.

“As the final stretch of this hard fought GOP primary bogs down into a delegate fight among party insiders and operatives that likely won’t be decided until the July convention in Cleveland, Trump’s singular star power appears to be no longer enough—and his campaign’s months-long lack of attention to other fundamentals is emerging as a hindrance to his ability to clinch the nomination outright.”

“A majority of Republican insiders say Donald Trump should not get the GOP presidential nomination if he falls short of winning a majority of delegates – even if Trump amasses more than any of his opponents,” Politico reports.

“Roughly six-in-10 Republicans said the party should nominate another candidate if Trump finishes with a plurality, rather than the required 1,237-delegate majority necessary to claim the party nomination.”
