Trump-bashing RINO dropped out of the presidential primary race in December.
Graham’s final RealClearPolitics national polling average was only .5 percent.
On Friday Lindsey endorsed Jeb Bush.
Lindsey’s .5% support could boost Jeb Bush above 5% in the polls – but not likely.
Social media was not so impressed with today’s announcement.

UPDATE: Donald Trump responds:
Jeb Bush, who did poorly last night in the debate and whose chances of winning are zero, just got Graham endorsement. Graham quit at O.
