This Week in Trump: Talkin' Bout a Contested Convention

1,237. That’s the magic number of delegates Trump needs to avoid a contested convention. After a stinging loss in Wisconsin, it’s increasingly unlikely he’ll reach it.

On the flip side, New York has a big say in the primary process. A white-hot spotlight will hit the state on April 19 – the day of the primary. And Trump is on track to win on his home turf. He's ahead in the polls with more than 50 percent of likely voters.

This week, we present an audio field guide to understanding the state’s primary. New York-based Republican strategist, David Catalfamo joins host David Furst to explain the gruesome details. But don't civics lessons go better with a musical soundtrack? We imagine the old educational cartoon series Schoolhouse Rock stepping in to explain it all with some info-packed musical numbers.
