This is a perfect example of how Democrats will vote for their candidate, warts and all. Republicans have principles to a fault and end up letting the other side win. The primary is the time to root out the devils. Short of doing that it is playing with fire to stay home and pout instead of holding your nose an voting. Just my opinion.
And, believe me, I have been on the other side of that in the past and have regretted it after I saw the damage done by my decision.
It would be nice to do, but Louisiana has no closed party primary. The open primary system was instituted in 1977, and with the present makeup of the legislature, there is little chance of changing it.
