But Trump is not willing to self-fund the more expensive general election battle. He recently signed an agreement with the RNC to bring in money from wealthy donors who can write checks for as much as $449,000, while giving his approval for super PACs to pick up the rest of the slack.

The problem is that fundraising networks don’t bring in hundreds of millions of dollars overnight. Romney, among the most prolific fundraisers in GOP history, spent years cultivating his donor network, so that by this time in the primary cycle it was well positioned.

The RNC has had a very successful election cycle fundraising, bringing in $144.8 million thus far, with $17.4 million in the bank as of April 30.

But the demands of running a presidential campaign, as charged to do by Trump, are going to require considerably more money, and fast. Republicans in down-ticket races wonder if there is going to be any cash left over to help them.
