The more I think about it the more I think we all put these Senators on too much of an intellectual pedestal. I think the most likely explaination is the simplest: those who voted for the point of order but yet also for the Cromnibus probably didn't realize that their vote for the Cromnibus was still in support of the President's illegal amnesty. That is, they were probably under the impression that the vote for the point of order was a seperate vote entirely. For some thing else entirely.
I'm more and more convinced with each passing day that there are indeed low information voters in Congress as well. It's the most charitable I can be really. Regardless it's probably right. I just can't see everyone in Washington being as clever as would be needed to believe in such a vast Establishment conspiracy.
No, most likely there are many sheeple in Congress too, led around by others. Remember these votes are done at the same time for everyone so no one really knows how another will vote. When they vote they do so themselves it's not as if Mconnel is pushing the button for them. So I think those who voted for the point of order but also for Cromnibus said to themselves at the Cromnibus vote as they were actually voting "Ok, now that Cruz got what he wanted so now it's time to vote for this OTHER thing that's more important. It doesn't have anything to do with Cruz anyway so it's a win win for me if I vote for this now". This uninformed decision explains also the three who didn't vote at all. They just decided "Yah, I'm not so sure how to vote here so I'm just not gonna vote".
So all in all this isn't bad for Cruz and Sessions. They just need to reach out to these uninformed more (meaning put more pressure on them and keep a closer eye on them to make sure they know how to vote next time). It doesn't mean these 9 are opposed to the true conservatives in any substaintial way. It just means they are the uninformed that simply must be educated more (or at least controlled better).
You can be sure McConnel is gonna be trying to cement his influence with them over the coming weeks. So Cruz better get to them first.
I like it that you left open the chance of them being brought over to the conservative cause.
