There are some higher scores, but 89.1% is pretty decent.
Collins by contrast is at 67%
I think you’ll find Rand Paul is among the lowest and yet he is best friends with Trump!
Why? Because Rand votes against any spending bills and they include those votes..
Collins represents a state that hasnt voted for a GOP presidential candidate in years, so even 67% seems unexpectedly high to me.
