No problem...we win when we put CONSERVATIVE candidates on the ballot. I’m not sure how it works in Colorado, but in many areas; the open primary system makes it nigh impossible to get conservatives on said ballot; because Democrats cross over to vote for RINO’s. This is a deliberate strategy that they implement every four years, and it needs to be stopped. The ‘stuffing’ you mention is also a serious problem. We need to get these resolved.
We have open primaries here (VA) and it can work both ways. Another influence is to send your usual political donation directly to the conservative candidate of your choice, and not let it be filtered through the NRCC etc. I maintain that the TP is a very useful and highly effective tool - the sheer number of like-minded people the TP has energized is awesome. The Dems know this, and it is scaring them witless. Witness their scornful derision - a sure sign that they are stung.
