2.His Brother,likely prodding.
3.Levin same as above.
4.Rush has exhibited a penchant for copying much of what Beck does these days.
5.Jealousy.I think Rush is very jealous of the Donald,this could be the biggest motivator.
Add it all up and it makes perfect sense.
I agree with you on the jealousy motive for Rush’s anti-Trump attitude. There may be, and probably are other factors as well, but that’s definitely a part of it IMO. When a real leader comes along, it kind of makes the pundits like Rush less relevant.
Rush has been considered, and probably considers himself to be a leader of the conservative movement, and yet what has really been accomplished for the conservative movement under his ‘leadership’? A lot of smug, self-righteous bloviating and whining. Not much else.
