I agree about the article. But I have serious doubts about the implication that crossover Republicans are split between Obama and Hillary.
I just got back from early voting. I saw a great many locals (we're in a small town) who I know are Republicans taking Demo ballots. I couldn't query them at the polling place, of course. But, prior to voting, I'd compared notes with quite a few. They were reasoning as I did, and voting for Obama in the primary.
In Texas, there's nothing to change or nothing to affect, if one votes in the Republican presidential primary. But, if a Republican votes Obama in the Demo primary, as a good many of my friends and I are doing, then it drives the stake into Hillary's campaign just a little deeper with each vote.
We live in a very Republican County and the area where we live is overwhelmingly Republican. I have to assume some were voting Dem just for this primary as well.
I couldn't do it - I got to vote on several referendums we hope to get passed, as well as vote for our Representative, hoping to get rid of the idiot dem who took Tom Delay's seat. We also have a Sheriff's race that is important.
On top of all of that, I got to vote for Fred Thompson. I won't vote for McCain until I have to.
