After yesterday’s North Carolina landslide and Indiana cliffhanger, most commentators have upgraded Barack Obama’s chances of securing the Democratic nomination from likely to (almost) certain. The next stage in the contest, assuming it gets that far, is next week’s primary for West Virginia, at which 28 delegates will be elected through a “modified” primary open to independents and registered Democrats.

Slate presents the Democratic race in seven (and a half) minutes.

Minus one week and two days, to be precise. Next Wednesday our time, North Carolina Democrats will elect 115 delegates, 77 by district-level proportional representation and 38 by statewide PR*. Indiana will elect 72 delegates, 47 by district-level and 25 statewide. Both are primaries, which have been doing better for Hillary Clinton that caucuses. However, the polls have Barack Obama ahead in both states – commandingly so in North Carolina (51.3 per cent to 35.8 per cent, according to Real Clear Politics’ fortnight average), narrowly in Indiana (46.3 per cent to 43.3 per cent). North Carolina will have a “modified” primary open to independents and registered Democrats; Indiana will have an open primary, meaning all voters can participate. And let us not forget Thursday’s caucuses for the Pacific island of Guam, at which three delegates will be selected by a closed caucus.

This post will be progressively updated to follow the count in the Pennsylvania Democratic primary, starting from when I get out of bed (by which time it might well be all over). Real Clear Politics’ poll average shows a slight narrowing in Hillary Clinton’s lead since last week, from 47.4-40.4 to 49.5-43.4.

11.30am AEST. CNN reports Clinton leads 53-47 with 20 per cent of precincts counted. Their exit poll, if I’m reading it correctly, points to a result of about 52-48. They called it a “win” for Clinton about half an hour ago, for what that’s worth.

12.30pm. Clinton has just given a speech to claim victory of one kind or another: she now leads 54-46 with 75 per cent of precincts reporting.

12.50pm. As Obama gives his speech, the CNN’s count clicks over to 55-45 with 78 per cent of precincts reporting. They are giving Clinton 52 delegates to Obama’s 36 on television, but their web page is holding back on 37-31.

2.20pm. With 98 per cent of precincts reporting, Clinton’s has a lead of 54.8-45.2, which is at the higher end of market expectations.

A merciful mid-campaign lull precluded the need for a “minus two weeks” thread, but things are well and truly picking up again now. Real Clear Politics’ Pennsylvania Democratic poll average has Hillary Clinton leading Barack Obama 47.4 per cent to 40.4 per cent, which is not as much as she would like. However, the most very recent poll from SurveyUSA puts it at 56-38 (UPDATE: Whoops, that’s not the most recent poll after all. There have been quite a few others since that have been around the RCP average). Statistical anomaly, or Obama’s elitist chickens coming home to roost? I report – you decide.

Another week, another Pennsylvania countdown thread. I owe Andrew Bolt a link, so see here for a revealing view of the Gallup poll trend as the Reverend Jeremiah Wright affair fades from view.

As Barack Obama weathers the Reverend Jeremiah Wright controversy, Hillary Clinton misspeaks. Compare and contrast …

Another thread for discussion of matters American. Since the last instalment we’ve seen Barack Obama win Mississippi 61-37 (19-14 in delegate terms), before running into his first bit of serious campaign turbulence courtesy of the audaciously hopeful Reverend Jeremiah Wright.
