still enough that seemingly unconditionally support him

You're absolutely right that the number of people in this camp is too damn high. Frankly, it's still high enough that he's winning the nomination despite waning support from more moderate conservatives, and that's enough that he will still be a threat in November. So, I guess in that respect it doesn't really matter if he has hundreds of millions of rabid supporters or 1 million rabid supporters and hundreds of millions of lukewarm conservative voters, it seems like he's still going to be on the ballot.

And frankly, my parents might still be rabid supporters and they just know better than to let that show around me and mine because they know his actions are indefensible and they are worried about losing access to their grandkids (with good reason).
