Well for a lot of conservatives, they've been convinced that there are more important things in life to protect like the principles of "personal responsibility", and "family values". And then there's those coded slogans like "Keep America, America" and "Make America Great Again" and "Build The Wall so I Can Safely Sleep at Night".
And let's not forget the classic Circle of Circular Logic scheme that the GOP imbues their followers with. The moment the GOP traps their victims in this mind-numbing merry-go-round, there's no logic or reasoning that will pull the hapless victim off of that ride. They're done for.
Fear and hate are emotional issues of which facts and the truth have absolutely no chance of overcoming, short of having some kind of personal earth shattering moment of clarity where even one's religious faith comes into question, and how often does that occur? The GOP understands this full well and have been quite candidly exploiting this characteristic of human nature to their full advantage when it comes to keeping the faithful, faithful.
The GOP also forces the Dems to take the weaker defensive side of issues via baiting the Dems into fighting the GOP on the GOP's terms and on the GOP's turf. Of course, the Dems will half heartedly oblige, given the alternative of having to allow the GOP free rein over the narrative that influences where votes get check marked. This baiting tactic uses lies, rumor mongering, emotional catch phrasings with no basis in truth, baseless accusations and contextual flim flams. The GOP has turned this game of theirs into an art form and they are blatant about it because they get away with this shit all the time.
The Dems, for the most part, refuse to play this game to their chagrin and to their demise. A practical Kobayashi Maru scenario of sorts because fighting the emotion-tugging lies the GOP spreads with the truth has little or no emotional return on value. Fighting the lies with lies will take the Dems onto the Repub's playing field, which is exactly what the Repubs hope for.
The reason the GOP has to resort to these kinds of underhanded tactics? It's because they cannot offer their base, their working class and their destitute constituents anything of value that actually improves their lives in the areas of economic opportunity, health care and educational advancements. And the reason for this is as we all know, the GOP is bought, owned and operated by the very wealthy. The GOP (the wealthy) need to feed off of the working class for their wealth, and they need their working class to be willing and compliant in this regard. Promoting the ability of their working class constituency to be independent minded, financially secure and very well educated turns their constituency into a threat. The GOP (the wealthy) can't have that. They need to make sure these opportunities are exclusively reserved for the wealthy and their children.
So simple to see, yet willfully ignored by those that are caught in the circular logic trap the GOP continuously has baited and set out for them.
