Ironically, in 2010, Trump donated $50,000 to American Crossroads, Karl Rove's Super PAC:

TRUMP, DONALD J NEW YORK,NY Trump Organization 10/6/10 $50,000 American Crossroads

[Jane Long]

Ironically, Cruz' biggest donor, Robert Mercer, gave $2M to Rove's Crossroads PAC. Cruz other large donor, Club for Growth, who Cruz has received $1.5M from, received $750K from Mercer.

When it comes to overall donations, Trump - who has donated to BOTH parties, in states where he has businesses - is a piker, when you compare his $1M (overall, throughout the years) to other PAC/campaign donors.
