You're correct, in the sense that Trump doesn't seem to be building his base. However, when you watch what's been going on, his enemies in the Democrat Party have been doing the job for him. Their shenanigans since the Election have been slowly but surely driving people into his camp. Now, if he and his "followers" can succeed in not driving them back out he's home free in 2020.
Very good point
@Cyber Liberty Fortunately for the GOP at this point, politically, the dem base is not growing
either, just getting more rabid, by the minute, Thank You President Trump, no sarcasm intended.
I seriously doubt the dems will allow hellary to run again, their new nominee may energize their base, erasing the Sanders dilution and consolidating the black vote and Trump has not done much, IMHO, to endear the Conservatives to his cause and he will need us for his re election, if this comes to pass. It's way to early.
