Oddsmakers are bullish on California Senator Kamala Harris' 2020 presidential chances.

According to online betting site Oddshark, Harris has surged into a tie with Vermont Senator Bernie Sanders for the best Democratic odds to win the 2020 presidential election.

President Donald Trump still has far and away the best odds at +140 (meaning a $100 bet would earn $140 for a Trump win) and is followed by Sanders and Harris at +1200 apiece.

Vice President Mike Pence and former VP Joe Biden are tied for the third best odds at +1400, and Senators Elizabeth Warren and Cory Booker are tied for fourth at +2000.

Oddschecker, a site that compares odds across a number of prominent betting sites, also found that Harris consistently receives better odds than her Democratic counterparts.

The site gives Kamala Harris 9/2 odds to win the Democratic nomination, followed by Joe Biden with 11/2 odds.

Even though Oddschecker gives Harris better odds than Sanders to win the Democratic primary (9/2 to 6/1), the two both have identical 9/1 odds to win the presidential election, trailing President Trump who has 11/8 odds to get re-elected.

Harris has long been rumored to be a presidential candidate in 2020.

A May report from The Hill stated that Harris was gearing up for a "shadow campaign" in red states to help 2018 Democratic congressional candidates campaign for the midterm elections in November.

The California freshman senator is also set to release a memoir in early 2019, a move that has further fueled 2020 speculation.
