Excerpts: "Biden continues to lead in the national polls, still holding at roughly 30% of Democrats, but Elizabeth Warren made a huge jump, now alone in second place and closing fast on Biden.
...The first three 'early states' – Iowa, New Hampshire and Nevada – are now all very close races. Warren is slightly ahead in Iowa, more so in New Hampshire and Nevada is a three-way tie.
...Biden continues to dominate South Carolina, the only early state with a strong African-American presence, his strongest demographic and his 'firewall.'
...Bernie Sanders suffered a heart attack while on the road, bringing the age of all three leading candidates into sharp focus; Sanders, while sidelined, lost some ground nationally and in Iowa.

Two emerging stories have gone largely unreported: (1) The rise of Pete Buttigieg in Iowa. The ground reports on Pete in the Hawkeye State have been glowing for months, but none of that turned into poll momentum until this past month, when three separate polls had him in double digits and catching up to Sanders. If Mayor Pete is able to snag a top three spot in the Iowa caucus, that would be a significant development. (2) Super Tuesday. With everyone focused on Iowa, New Hampshire, Nevada and South Carolina, no one has been focused on the true prize. The early states have 155 delegates at stake, but Super Tuesday has 1,255. If Biden can survive the first three contests and win South Carolina (where he continues to lead), he is well positioned for a delegate haul on Super Tuesday."
