Pompey was snubbed when the land bill he proposed to accommodate his veterans was defeated. The Senate looked down on Pompey as beneath their class – a plebian by heritage and only now elevated because of his father. They distrusted him fearing he would try to use his army to overthrow the government.
Finally, Crassus was snubbed when he supported the re-write of a tax collection contract favored by the knights. He got Cicero over to his position, but Cato killed the bill.
