The Jefferson Jackson Dinner is a big deal in Iowa presidential politics. With thousands of active party supporters there, each candidate gives a speech. it can make or break candidates. According to David Yepsen at the Des Moines Register, Obama came out on top in last night's speechifying:
It was one of the best of his campaign. The passion he showed should help him close the gap on Hillary Clinton by tipping some undecided caucus-goers his way. His oratory was moving and he successfully contrasted himself with the others - especially Clinton - without being snide or nasty about it. [...]
Obama was particularly impressive Saturday night. Should he win the Iowa caucuses, Saturday's dinner will be remembered as one of the turning points in his campaign in here, a point where he laid down the marker and began closing on Clinton, the national frontrunner.
