That just isn't true.
Republican candidates have lost significant support in every single special election since Trump took office, even the ones they won. Massive shifts of 20 points or more in the opposite direction.
Candidates personally endorsed by Trump have been met with defeat.
I don't think @waiguoren is overestimating the importance of the wall. The wall was the main campaign promise from Trump without question.
I think he's underestimating a Trump's supporter's desire for measurable results in practical reality. Even with no wall, they won't care. Hell he can still run on build the wall since no wall has been built and they'll still love it.
They just like simple slogans.
It's his central campaign promise. Immigration is the #1 issue for Republican voters as shown by multiple national polls. I think you're underestimating it.
The economy is cyclical. There will be a downturn under Trump's watch. He failed on health care. He can't screw up immigration.
Republicans have lost massive support in the special elections. Look what just happened in OH12. That is a deep red district and the Republican barely held on. This is a bit misleading because Trump has sacrificed wealthy suburban support for working class support, but overall it's been bad for the Republicans.
What happens every year to the party in power? They lose seats.
Dem losses with high turnouts, are still losses.
I’d argue they’re doing ok, it will most likely look better than Obama’s off year elections.
