I think the DNC screen all politicians for the UniParty. You can generally tell who the Republican (and occasional Democrat) politicians are that they don't control, thus least approve of by the way MSM coddles or criticizes them. Santos is an unknown legislative entity going forward. Was EVERYTHING a lie - including his political positions? - will he sell his votes? - is he an operator with an agenda? The election of Santos was absurd, Santos history is absurd, Rep. Santos for 2 years should have surprises.

Sure they do. They have a stringent screening process. ANYONE actually for the Country gets whacked out in a primary or General and denied funds.
