It seems like a logical pairing: Republican donors who despise Donald Trump, and two GOP presidential hopefuls sticking it out to keep him from the nomination.

Yet such a financial cavalry never arrived for Ted Cruz and John Kasich, ignoring their impassioned pleas for financial help.

Donors who gave as much as allowed by law to establishment darlings Jeb Bush or Marco Rubio have mostly disappeared from the political landscape, according to an Associated Press analysis of campaign finance records. Less than 3 percent of the nearly 14,600 donors who gave the $2,700 limit to Bush or Rubio have also ponied up the maximum amount to Kasich or Cruz.

By not writing those checks, they’re depriving Cruz and Kasich of as much as $39 million each in their final push to topple Trump, who has formidably deep pockets and has loaned $36 million to his own campaign.
