Well, the popular vote count is suggesting the GOP base *is* shrinking -- even Her Awfulness looks like she pulled a couple million more votes than Trump.  Rational analysis of the campaign that looks beyond the "racist conspiracy" trope would grasp that Clinton ran an incompetent campaign characterized be hubris, arrogance, and groupthink about her inevitable victory taking precedence over political strategy.  Clinton thought she was owed union labor votes, black votes, Hispanic votes, women's votes, Millennial's votes, etc., so she ignored the "nowhere else to go voters" in favor of more face time with the donors.  Every single one of those categories either saw serious defections to Trump or serious dips in turnout.  Trump was probably the only Republican that a candidate as flawed and unappealing as HRC could have beaten, but it takes an idiot of HRC's level to lose that race, and that's just what she did.
