I have felt this for some time with Trump, but I believe the solution for the problem has already been dealt with.
Cruz has that grassroots organization you’re speaking of, and he and Trump have been meeting for months.
As/if Trump declines you’ll see Cruz pull those disgruntled Conservatives, and Reagan Democrats to him.
It’s going to take a delicate balancing act to shift the support, but I believe we have already seen the beginning, and will see more in the debates.
Just hearing Cruz inspires people, and unfortunately most Americans haven’t heard him yet. Watch for that to change after the first debate.
If Cruz has a Reagan Democrat appeal plan, he'd better roll it out right quick.
