A candidate for their party's nomination just can't seem to get a win.  What's their plan? Look three weeks forward on the campaign calendar, pick a big state to make their firewall, and spend three weeks in that state -- to the exclusion of all other primaries -- trying to win it.   A sound plan?  One might think it's a plausible strategy.   Except... We've seen this before.  It was just done and failed miserably -- by a New Yorker no less.
