I don't trust your answers. I can't understand how you would know so much about both Nevada and Ohio if you're really an impartial observer... If you're not, you should make it clear that you are a cna partisan and are presenting events as the cna has presented them to you.
Your answer to number 1 seems like splitting hairs. Why do cards make something more democratic? I've read posts by a CA nurse Sherwood on allnurses.com describing CNA organizers plying nurses with trinkets and pizza. The way I understand the Ohio agreement, no such bribes were allowed. I think bribes are a bigger deal than cards in terms of democracy. (Have a piece of pizza, sign a card honey! It's just a card to show you want us to bring more pizza into your hospital...) No one was trying to persuade nurses either way in Ohio until the CNA showed up.
Your answer to number 2 is clearly misleading, as you asked CHP nurses to vote no, anti-union rhetoric if I ever saw any. This is on the pdf that is posted on your website. If seiu asked nurses to vote no, that's sad, but it is not an excuse for you to hurt nurses in Ohio.
Nurses should care which union represents nurses and hospital employees in their state; without uniting lots of nurses in their own state how can they make their voice heard in politics?
As for #4, if a few nurses working with the CNA for a while makes seiu's interference in Nevada troubling, then 3 years of work with SEIU at chp makes CNA's interference even more troubling.
