The reason that Trump is doing so well with Republican "moderates" is simple

[0rganism]

3. it's even simpler than that

the Trump supporters are the racist contingency, voters who left the Democrats in the '50s and '60s, and were swept up into the Republican party through Nixon's "Southern Strategy". they hold moderate views on fiscal issues, believe government still has a role to play in bettering their lives, and resent having their votes taken for granted by the establishment interests (banksters and industrialists) for 5 decades.

every day since Jan. 20 2009, they've woken up with a black president, and that really pisses them off.

which candidate had the "courage" to call out president Obama as illegitimate? not just the tired tea party line that he was doing unconstitutional things, but that he was actually unqualified by birth to be the president? Trump.

which candidate promises to support the metaphorical walls they already build in their minds and souls with a real border wall? Trump.

which candidate sends up the dog whistles for reverting to segregationist policies? Trump.

and that's who they support now.
