In this March 14, 2016, photo, Republican presidential candidate Donald Trump speaks at a campaign event in Tampa, Fla. Trump says he’ll raise money for the Republican Party and there’s a good reason why: It has the resources he lacks for a general election. Trump’s victories this week make it much more likely that he’ll be the party’s presidential nominee, probably facing off in November with Democrat Hillary Clinton. That raises the question of how a so-far &quot;self-funding&quot; Trump would pay for could be a billion-dollar campaign.
