David McIntosh, President of the conservative political advocacy group The Club for Growth, joins Morning Joe and talks with Mike Barnicle about his organization’s efforts to stop Republican presidential candidate Donald Trump from becoming the party’s nominee. “Part of your theory would lead many experts to believe that Senator Ted Cruz (R-TX) would lose more states in the fall than would Donald Trump. So, why not go after Ted Cruz on an equal basis?,” asks Mike. Listen to McIntosh explain why his organization is anti-Trump and supports Senator Cruz.
