Question about "crossover" voting

[MGKrebs]

As we all know, the repubs pulled Dem ballots in the primary here in Georgia last time in order to keep McKinney out of the General election. Is something like this possible in a presidential election?

- How many states have "open" primaries?
- Are all states "winner take all" regarding delegates?
- If the repubs get even 2 or 3 states to commit their Dem delegates to someone who otherwise is way behind, how does that play out at the convention?

I don't understand the electoral college very well. I could look it up (and I probably will), but it seemed like a good time to discuss this, because others might not understand it either.

1. Actually, the freeper plan

Was to crossover vote all over the US for Sharpton.

2. All states are proportional under Democratic rules

I don't know the statistics on open primaries offhand.

3. What I want to know is the rate of crossover voting in the 2000 election

when ever I google the topic I can only find info for 1996 and earlier. I think general wisedom says that Republicans interfer with Democratic primaries by a factor of atleast two to every Democrat that does the same.

4. More...

This is from the FEC site (my comments in italics):

"The political parties (or independent candidates) in each State submit to the State's chief election official a list of individuals pledged to their candidate for president and equal in number to the State's electoral vote. "
Does this mean that the Democratic party supposedly names electors that will vote for whatever Dem wins the primary in their state? Or do these electors not get named until after the convention?

edit: I suddenly realize that this doesn't make any sense, because the electors will be AT the convention. So they must be selected prior to the primaries?

"After their caucuses and primaries, the major parties nominate their candidates for president and vice president in their national conventions "

"Whichever party slate wins the most popular votes in the State becomes that State's Electors-so that, in effect, whichever presidential ticket gets the most popular votes in a State wins all the Electors of that State. . "
