It isn't really liberal or conservative math, but "primary math." Most of America is somewhere in the middle, politically, on most things. The formula is basically: partyBase + majMiddle = winner.The conservative math confuses me. A candidate that doesn't have popular support (like Cruz or Kasich) during the primary somehow has a better chance of defeating the eventual democratic candidate... nobody wants to admit it, but there are blue collar democrats that find their party no longer directed toward their goals (doesn't that sound familiar?)... some of these people will cross over and vote for a Trump candidate much like they did for Reagan.
It has long been a problem for Republicans, and this cycle for Dems, too, apparently, this cycle, that the base primary voters choose people that don't do well in the general.
Trump is basically leveraging the middle with his crossover support. Hard to predict what will happen in the general with that.
