Politico: “Concerns are mounting among top donors and party elites that an influx of huge checks into the GOP primary will hurt the party’s chances of retaking the White House. Long-shot candidates propped up by super PACs and other big-money groups will be able to linger for months throwing damaging barbs at establishment favorites who offer a better chance of victory, the thinking goes. Already, big-money groups have raised about $86 million to support a handful of second- and third-tier candidates.”
