No, but a national majority party is always going to have two 'wings' to it.
The Democrats are now the minority party because they destroyed their 'conservative' wing by forcing it to vote for Clinton tax raises and gun control.
The best way to handle RINO's is to make them irrevelant in the Party by having an overwhelming majority of solid conservatives.
Yet, the reality of national politics is that some regions of the nation are more liberal then others and will only elect RINO'S.
A RINO is therefore better then a Democrat in that same seat if that RINO is only needed to maintain our majority and is not consulted for policy decisions.
Correct - if the Republicans have a simple majority or better, then the Republicans get to appoint committee chairs, the Speaker, the officers, etc. This allows for Republican legislation to move. If Democrats had a simple majorty, then their committee chairs can bottle up Republican legislation effectively indefinitely.
