yes.
but it is not always that way. if the democrats have important primaries, they will vote democrat. in our primaries, they are open, but you can only vote for one party. you cant vote republican for one race and democrat all the rest, it invalidates the ballot.
The dim primary in MS was boring. Lots of them crossed over and voted for the GOPe guy.
They knew the GOPe guy was just the same as the dim anyways.
