As far as Bush was concerned he was a fool about 'read my lips'... Bush believed the democrats. Bush thought they were honorable.
No one on our side believes that now.
We even know they hire people to write letters out of their War Rooms to our Congress people pretending to be constituents.
Everything about Democrats is a paid lie... atroturf evil... all illusion. After we expose the corruption of the Clintons and Deep State we'll go after the paid trolls in the Democrat Party... they're all over the internet... using our words to make their filth sound more authentic. It'll be fun to out them...but for now there's bigger fish to fry.
I'm still for Trump because we don't have and haven't had better for many decades. But,I've been getting phone calls, emails & text-messages today from many friends/relatives who were Trump supporters/voters (some who I helped win over) and all of them say he “sold out”/”folded”/etc and can't be trusted again.
The unimportance of the issue to you is not representative of the base that got Trump elected. Breaking this, his most repeated, promise was the surest way to lose in 2020.
If you want to picture why, just recall all the 1992 Clinton ads with Bush making his “Read my lips...” pledge.
