"Trump led Republican party"?  

The Republican party who was willing to take Cruz to avoid Trump"

The Republican Party that spent millions of dollars to go for anyone but Trump?

If the Republican Party was 'following' Trump, there would already be a 'Repeal and Replace"; there isn't.

If the Republican Party was 'following' Trump,there would already be a Congressional Bill on DACA; there isn't.  

Your party bias is sneaking into your perceptions.  

Trump is no more a Republican leading other Republicans than Sanders is a Democrat leading other Democrats!

The 'details' will have to come out.  There isn't a "tax reform bill" in the entire world that is only 9 pages long!

This is just the usual knee-jerk by the Democrats--and by you!
