With all due respect to your point, in years past, I would write Trump off. But, this is no ordinary election. The future of our country is at stake, and we have not had in the past 2 election cycles, a candidate who was willing or able to take it to the opposition. So, we ended up with a dictator in the WH. This cycle is different, and we need someone who fights back. No more Mr. Nice Guy, no more taking the high road - how has that worked out for us? It hasn’t. So, if people want to attack Trump - they better expect to get it back, because Americans are fed up with the nice guy routine.
Gingrich attacked the opposition and media relentlessly...it isn’t just Trump.
But again, what good is attacking Lindsey Graham when he is irrelevant? Focus the fire on the enemy...Hillary, Jeb, Sanders, etc...
