I suspect Rachel is too young to understand the error of her ways.
Right now, she is still falling for the "come on guys, can't we all get along" siren call of the RINO. It is tempting. The argument is that the RINO won't betray us THIS time (he promises!), and besides, if you don't vote for the RINO, then the REALLY bad guys win.
Many of us are done voting for bad guys. Period.
After she has been through a few more election cycles, and realizes she's already seen this movie 4 or 5 times now, and she already knows how it ends, then she will come to understand why the only thing she can do is leave the theater, and stay out until the GOP has a new script and makes a new start with new men and women of Conservative values and convictions.
