As I write this, Ted Cruz has just won the caucuses in Kansas and finished a pretty good overall Saturday in which he inched to within 83 delegates of Donald Trump in the nomination race. The count now stands at 378 for Trump and 295 for Cruz, with Rubio still lagging way behind at 123 and John Kasich barely registering at 34.
Strategically, that might explain why Cruz is the only Trump rival who is rejecting any notion of a contested convention to take the nomination away from Trump - if it comes to that. When Cruz says the only real way to beat Trump is to beat him at the ballot box, the numbers tell you pretty clearly that he's the only candidate who has any chance of doing that.
