I can't quote any numbers but I believe you are correct in that the MAGA idiots that won were considered safe for the party even if they ran Adolph Hitler. So, they don't count toward successful endorsements for Trump. I mean Marjorie Greene got like 66% of the vote in her district. Who votes for that? And that is not because they back her on policy, she has none, her platform is to say crazy and stupid shit and get as much media attention as possible. Matt Gaetz won getting just over 67% of the vote. He trafficked 17 year old girls. Who votes for that? Republicans do not stand on morals, ethics, or values. They could not care less about that. They will vote for complete scum because they have an R next to their name. 

Ken Paxton the completely corrupt Attorney General in Texas, that actually ran away from a process server while hiding behind his wife, won reelection fairly easily. It was headline news how corrupt this guy was, people still voted for him. Why? Because he is a Republican and in Texas they do not care what you do as long as you do it as a Republican, they will back it. It's an embarrassment to the state but hell, they elect guys like Greg Abbott and Ted Cruz over and over. And the Democrats should sort out that Texas does not like Beto O'Rourke because he has now lost to Cruz and Abbott, two total scumbags, so find someone else.
