Generally - yes. They won about 80% of all races. But with Bwownback's support and financial assistance they had from numerous conservative PACs - that could be expected. In addition - the Republican primary electorate in most states (except some North-Eastern, but even there - somewhat more conservative then in the past) is not even conservative, but outright very right wing. So - it's more surprising that some moderates still managed to win and some new were elected. But generally - yes. May be that will lead to election of somewhat more Democrats..
