McCain and Romney lost 62-36, so not terrible numbers for Cruz. Great numbers for Kasich, though
Numbers for usually-solid states can show the weaknesses of some Presidential nominees. Except for the freakish situation in Indiana in 2008 (the worst economic meltdown in nearly 80 years, and a horrible time for the RV business due to the combination of a credit crunch and high fuel prices as well as an overall downturn in the economy which caused places like Elkhart to go Democratic) , it is safe to say that the Republican winning by 15% or more in Indiana is probably winning nationwide. By 10%? He's probably losing nationwide.
Invert this for Maryland.
