re: Ironically, white people appear to be where Trump is weakest

I kind of agree with OP but with the 3 groups you have only two choices and for two of these groups (Boomers and Christians) I don’t even see how they could choose Kamala over Trump when those are their only choices.
Boomers would be under greater pressure under a Kamala administration with risk of an event worse economy and a disastrous foreign policy. Both of these would be better under a Trump administration as they were during the last one.
Social conservatives and Christians just have to realize the abortion issue isn’t getting put back in the bottle at this point. It’s a state issue now where it should have been from the beginning and Trump has said he would not interfere. Kamala said she will do whatever she can to reinstate Roe. I just don’t see how this group would pick Kamala over Trump.
At the end of the day single issue voters are the worst because it’s just not that simple. All things considered you have two choices and most of the people in these two groups I believe can see thru Kamala’s BS and will do the right thing.
