In a span of about 12 hours, Americans were given definitive evidence that the Republican Party is now in thrall to its most ideologically and tactically extreme forces while the Democrats still look to the center ground and to compromise.

GOP establishmentarians had anointed Rubio as their savior, figuring the young and eloquent Cuban-American could cloak his very conservative positions under the appealing mantle of youth and diversity. It didn't work.
