If it became commonplace it could seriously limit the parties options for the general.

Schweiker was seen as a desperation move. i.e. : Relatively liberal. To offset R's perceived paleo-neanderthalism.

It didn't work for Reagan... but it is NOT w/o precedent.

But even Reagan waited 'til closer to the convention.

Like Reagan early picking Sen. Schweiker for veep in 1976.

the candidate is selected at the convention.

...protect the Democrat, I think the Party is much more divided now than we thought a month ago. There was a sense of "unity", perhaps false sense, but now I'm not so sure. DWS may have understood that the rancor within the Party was going to surface soon. However, she miss calculated just how intense the blowback from her 6 debate strategy would be.

The portayal of a "unified" Party was smoke and mirrors and the divisiveness was bound to boil to the surface right away.

said to her: "Don't be shocked by those cats -- they're just like Democrats. It looks like they're fightin' but they're just making more Democrats." I've been a DEM since 1960. Don't recall a time when the party was united.

"look at the Dems vis-a-vis the Rs." I think DWS's miscalculation unecessarily dialed up the divisiveness.

If you need to announce your running mate to get votes in the primary, your campaign is in trouble.

that Warren would want to share a ticket with Biden any more than any of the others. Has she really said anything about her interest, or non-interest, in being vp? She hasn't endorsed any candidate running, and I haven't heard that she's urging Biden to run, either.

I also don't know why anybody would STILL be pushing Biden at this point.
