The key to your last statement is that half of the party can't see and the other half, do and agree with this presidents "fundmentally transforming" the United States of Amerika. The evidence of that was the vote the other day that supposedly put back in their platform that Jerusalem was the capital of Israel and their support of God. It took at least three attempts to get that through and it was clear that at least half of those that were on the floor voted no.
The DemcRAT party is not the party of our fathers and mothers in the 50's and 60's. The DemocRAT party is now made up of at least half that wish the federal government was more of a dictatorship or oligarcy rather than a representative republic.
