Democrats as a group cannot win unless they cheat, steal, deceive. It is in their nature to be dishonest. The end justifies the means! I say Democrats as a whole. There have been very few honest Democrats. The same percentage that are equal honest the same percentage of Republicans who are dishonest.
Leftists follow the policies of their ideological father, the father of lies. There is no truth in him, he speaks his native language when he lies.
Some leftists have fooled themselves into thinking they are on the side of the angels. The “good” ends justify being dishonest in order to achieve them, and Uncle Screwtape laughs his tail off.
The few honest democrats don’t realize they are really conservatives.
