5 people to watch
1. Mark Warner. Keynote speakers tend to be those viewed as the future leaders of the Democratic party (See Obama, Barack, 2004), and the former Virginia governor now running for U.S. Senate will surely be a leading Democratic presidential contender in 2012 if John McCain wins in November.
2. Bill Clinton. Hillary Clinton knows how to be gracious when it's demanded. But her husband still seems to hold a grudge and will have the Obama loyalists nervously watching his every word. Watch Bill Clinton's speech and then try to guess who he'll vote for in the privacy of the voting booth.
3. Hillary lovers. Particularly older, white women whose enthusiasm (or lack thereof) for Obama may prove critical in November. Does he sweep them up into the fold in Denver, or leave them still wounded and ambivalent?
4. Michelle Obama. She has been a magnet for criticism and controversy, despite being a charismatic speaker and Jackie-esque mother and wife. Can she redefine herself for the masses?
5. Sen. Bob Casey. Democrats refused to let the Pennsylvania senator's dad speak at the 1992 national convention because he wasn't sufficiently pro-abortion rights. But now his son, another pro-life Democrat, is a featured speaker, reflecting the diminishing influence of abortion rights activists. Even the platform includes a nod toward pro-lifers.
5 stories to watch
1. The mood. The convention is all about showing harmony and unity, and this one comes after Obama barely beat Clinton in a hard-fought primary. Everybody will be watching the Clintons and their loyal followers to see if they're fully on board Team Obama or thinking more about another Clinton campaign in 2012.
2. The comfort factor. Obama is still largely unknown to many voters, so a big chunk of the show in Denver will try to flesh out his exotic biography to make uncertain voters more comfortable. He could effectively cast himself as the personification of the American Dream, or, with another giant stadium rally he could fuel the Messiah complex story line.
3. The nominating process. After Florida and Michigan bucked national party rules with officially illegal — and boycotted — primaries and the nominee was nearly decided by a bunch of party insiders, look for serious discussion about changing the way the Democratic nominee is picked.
4. Change. In an election like this, can Democrats successfully portray themselves as agents of positive change or will they look like the same tired party with a new standard bearer? Infighting and unruly protests wouldn't project the kind of change many voters are seeking.
5. Tone. Four years ago, John Kerry decided against any serious convention attacks on Bush-Cheney, who returned the favor by ripping the skin off Kerry at the GOP convention. Keep an eye on whether Obama and his surrogates stick to Obama's lofty tone or try to pick apart McCain's maverick image to cast him as a continuation of Bush.
