Politico reports that "Ted Cruz and John Kasich have begun coordinating their campaign strategy to stop Donald Trump, an abrupt alliance announced Sunday night that includes Kasich quitting his efforts in Indiana and Cruz clearing a path for the Ohio governor in Oregon and New Mexico."

The Trump campaign fired back, blasting the "collusion" between the two campaigns.

270toWin: On its face, this deal would seem to benefit Cruz much more than Kasich, although its unclear how much overall impact it will have (or how long it will last). It might make a difference in Indiana, where recent polling shows a fairly competitive race between Trump and Cruz. That state offers 57 delegates that are winner take all (30 based on state result, 3 in each of the 9 congressional districts).

New Mexico and Oregon are much later on the primary calendar, and have smaller delegate pools that are proportionately allocated. Notably, the largest delegate prize -- California on June 7 -- is excluded.
