With Super Tuesday now behind us, 15 of the 50 states have voted. If this were the Indianapolis 500, only 150 of the 500 miles would now be completed. Donald Trump has won won a plurality of the vote in 10 of the first 15 states—while Ted Cruz has won a plurality in 4 and Marco Rubio in 1—but the Republican frontrunner hasn’t won a majority of the vote in any of them. Moreover, on Super Tuesday, Trump’s percentage of the vote was more often in the 20s (in three states) than in the 40s (in two). In short, it’s time to dig in and fight, not give up and quit.

Still, one must grant this much: Trump will almost surely win the GOP nomination if Cruz (the clear second-place candidate at this point) and Rubio don’t start doing a better job of conveying to voters what they’re for.
