The first is whether the GOP establishment will pool its resources to wage a scorched-earth television ad campaign to try and derail the front-runner. Such an air war never really materialized in New York, and would be massively expensive in California’s many media markets.

“Donald Trump will not be the nominee — if the ‘Never Trump’ forces get serious,” Kasich adviser John Weaver said Tuesday night as his candidate was being routed. “They weren’t serious in New York and allowed Trump to get over 50 percent in numerous districts where he could have been stopped,” Weaver added. “Continued lack of engagement by ‘Never Trumpers’ could allow the Trump campaign to get back on track.”…

Underlying the carping is a fascinating civics debate. Trump’s position, distilled to its essence, is that in an era is which almost every state chooses delegates via caucuses or primaries, the candidate who wins the most contests and the most delegates should earn the party’s nomination. The competing argument is that the percentage of delegates Trump has attained actually exceeds the percentage of the popular vote he has received, and that the current process is in place for a reason: namely, so party leaders can choose the strongest nominee in the event there is no consensus candidate.

Here’s a third idea: Cruz won the Republican primary in his home state of Texas, while Kasich carried Ohio. Trump lives in two places, New York and Florida, and he was victorious in both. California is neutral ground. It’s also the most populous state in the union. Let’s let voters in Reagan Country pick the GOP nominee.
