So this is not a news story about them endorsing Biden - it is a news story about the social media mob being mad at them for not doing so in order to create a headline to give the impression they may do so - designed to divide the GOP on the eve of the election.
And based on the comments so far it was effective. A manufactured “news” story based entirely about comments made by some in the social media mob and nothing Bush has actually said or done in relation to an endorsement yields the same reaction as though an endorsement was made. It is a testament to how effective MSM propaganda still is - even here on FR.
Bingo!
