Now I have dined and enjoying a beer, so, to the point:
All the info you allude to is available, on CD, from the registrar, to any legitimate candidate. The amount of info one is allowed is based on the particular race one is a candidate of. If statewide, then, yes, can get statewide registrar info.
The question is, what is someone going to do with it?
Who is prepared to commit to a year of shoe leather ?
Who is prepared to donate time?
In the end, it comes down to the already established laws, the most votes wins.
Two years.
Who is prepared to donate time?
The conservative complainers.
That is exactly what the various levels of party structure are for....only they used to do it with paper lists and telephones.
