I don’t like the caucus idea. I much prefer a straight vote by the voters. Less chance of hanky-panky.

That's fine in closed primary states, but in states like Georgia where there is no party registration, there is no way to keep non-Republicans from performing the hanky-panky.

I'm neither defending nor repudiating this view... I'm just pointing out...

From a state party perspective, open primaries are a way to attract more voters to the party. The rationale is "once we can get them pulling the R lever and investing themselves as Republicans, we have a shot at keeping them."

I know of no evidence to support this belief, nor do I have evidence that "shenanigans" associated with cross-over voting in primaries has any impact.
