I am the Cory Booker precinct captain for my precinct in the River Bend neighborhood of Des Moines. When I heard he dropped out last Monday morning, I was gutted. Senator Booker was a unique candidate of hope in a sometimes angry field.

I was so firmly in his camp, I told people I didn’t need a second choice, I only needed to work hard to make him viable in my precinct. So after he left the race, I was lost, and I decided to go yell at a billionaire.

I believe Senator Elizabeth Warren would make the best president out of all of the candidates. So after spending more than a year carefully listening to candidates and watching their campaigns, I am excited to commit to caucus for Warren.

I have been a fan since she first appeared on the Daily Show, back when President Barack Obama reached out to her for her expertise and integrity to help save America in the wake of Bush’s 2008 recession, a recession that hit both of my parents pretty hard.

I watched as she helped put together a new agency to protect consumers, and how she got elected to the Senate after Republican senators blocked her from leading the agency she helped create.

The first time I saw her speak, and read her book, was a half-dozen years ago.  I wanted her to run in 2016.

My father used to say the most optimistic person is the guy on the brink of bankruptcy. He’s always thinking the next sale or the next deal will turn everything around.

Cory Booker remained “incomprehensibly upbeat” on the campaign trail, in the words of Rebecca Buck, who spent a year covering him for CNN. The senator from New Jersey wasn’t just another unsuccessful candidate falling for his own spin. Booker made believers out of many who were closely watching the campaign.

The Des Moines Register released its latest Iowa poll by Selzer & Co on Friday night. The results: the closest four-way race in Iowa caucus history. 

Before looking at the numbers, a reminder: a 5-point gap between first and fourth isn’t statistically significant.  The Selzer poll is widely regarded for a good reason, but the first thing to know about Iowa is we really don’t know who is ahead. 

The second thing to know: Iowa may have never been as important as it will be in 2020 (more on that in a minute).

With the Iowa caucuses less than a month away, and millions of future voters relying on Iowa to help shape the future of the Democratic field, now is the time to hear why Cory Booker has a rapidly expanding network of caucus goers, the largest number of local endorsers in Iowa, and is ready to heal our nation.

CBS/YouGov ended the Iowa polling drought (the longest drought since 1984) on January 5 with a new poll. 

The big news is not the trial heat numbers (23 percent each for Joe Biden, Bernie Sanders, and Pete Buttigieg, 16 percent for Elizabeth Warren, 7 percent for Amy Klobuchar). The big news is that only 31 percent of respondents have definitely made up their minds.   

Here is why this matters:
