Thanks to the Chicago Tribune, June 3rd, 2016
for fleshing out this list and the statements from
these pols. I'm certain there are more (-ad infinitum?)

--Aaaand the number of names will just roll on,
disavowing the Donald, courtesy of the newly-
awakened realization republicans of note have arrived
at--minorities vote, there are a LOT of them, most voters
are probably not racist, the democrats COULD
continue to keep the White House after November,
etc. ...Oh, yes, such racism, intransigence and ignorance
COULD cost some of these powerful republicans their
cushy seats in DC. How they howl as they scurry away
from Trump--is a "dump Trump" in the offing come July?

Regrettably, I am forced to conclude this latest spate of
scoldings (posturings) are attempts to align with the sane
side (right side) of history at last, at least apparently.
The few early exceptions to republicans supporting
Trump weren't numerous, influential, vocal or powerful
enough, sadly.

Memo to establishment republicans late to the party:
I can't/don't/won't believe you--where were you last year,
last month, last WEEK?
