After several months of campaigning, the Iowa caucuses are less than a month away. The crowded field of presidential candidates has dwindled, yet there are still 13 Democrats vying for the nomination.

The most recent betting odds from Bovada show former Vice President Joe Biden with the best chance of winning the Democratic nomination at +200 odds.

However, Vermont Sen. Bernie Sanders is not far behind Biden with +220.

Massachusetts Sen. Elizabeth Warren comes in third at +600. New York business magnate Mike Bloomberg, who has spent a great deal on media advertisements, has improved to +700, while former Mayor of South Bend Pete Buttigieg has become more of a longshot at +1000.

The Democratic field continues to get smaller, with former Housing and Development Secretary Julian Castro dropping out on Jan. 2 and spiritual author Marianne Williamson suspending her campaign on Friday.

Candidates are withdrawing from the campaign trail as the Iowa caucuses looms on Feb. 3. A recent poll from the Des Moines Register/CNN/ Mediacom shows Sanders in the lead for the first time. The survey says that 20% of Iowa Democratic caucusgoers would vote for Sanders in the primary, with Warren at 17%. Buttigieg at 16%, and Biden at 15%.

Prior to the Iowa caucus, there will be a Democratic primary debate on Jan. 14, which is also taking place in Iowa.

Biden, Buttigieg, Sanders and Warren have made it to the debate stage, along with businessman Tom Steyer and Minnesota Sen. Amy Klobuchar. In order to qualify for this month’s debate, candidates needed at least 225,000 individual donations, along with hitting 5% in at least four national polls or at least 7% in two early-state polls.
