They aren't simply counting heads, since Idaho Republicans appear to solidly control both chambers: 28-7 in the Senate and 59-11 in the House.
They expose many "Republicans" for who they really are: liberals who put an (R) after their names on the ballot because they'd never get into office as a (D) in their districts. Plenty of voters are fooled, and this sort of thing is hardly limited to Idaho.
Thanks for posting that link.
The Institute for Legislative Analysis is a good source of information. It reinforces my belief that RINOS are Democrats.
“It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.” ~ Sun Tzu
