Rep. Tulsi Gabbard of Hawaii announced Thursday that she was ending her bid for the 2020 Democratic nomination. Gabbard will throw her support behind former Vice-President Joe Biden.

Joe Biden swept Tuesday's primaries in Arizona, Florida and Illinois. When all is final, he will likely have more than doubled his delegate lead over Bernie Sanders. 

As of this morning, Biden has just under 60% of the 1,991 delegates needed to win the nomination. Sanders would need to win about 63% of the remaining delegates to win the nomination. The increasingly difficult math, as well as a presidential contest essentially now on hold due to the coronavirus, has the campaign assessing how to proceed.  

Donald Trump has surpassed 1,276 delegates, clinching the 2020 Republican nomination.  Wins Tuesday in Florida and Illinois put the president over the top.

Trump has won every delegate thus far, except for one in Iowa. However, Iowa rules specify that delegate can vote for Trump if he is the only candidate nominated, which seems likely.

Democratic Polling Averages & Delegate Estimates

Joe Biden is polling well ahead of Bernie Sanders in each of three states going forward with their scheduled primaries. While Sanders is expected to earn delegates, the end of the night may see the former Vice-President's delegate advantage more than double.

The Road to 270 is a weekly column leading up to the presidential election. Each installment is dedicated to understanding one state’s political landscape and how that might influence which party will win its electoral votes in 2020. We’ll do these roughly in order of expected competitiveness, moving toward the most intensely contested battlegrounds as election day nears. 

The Road to 270 will be published every Monday. The column is written by Seth Moskowitz, a 270toWin elections and politics contributor. Contact Seth at s.k.moskowitz@gmail.com or on Twitter @skmoskowitz.

Nebraska

Nebraska is all but certain to vote for Donald Trump this November. The state, however, is one of two that awards Electoral College votes by congressional district. Nebraska’s second district is far more competitive than the state as a whole and could prove decisive in a close presidential election. As such, this week’s article will be a little different than usual. The first half will focus on Nebraska’s history and political landscape at large and the second half will zoom in to the competitive Omaha-based district.

Road to Statehood

Georgia has rescheduled its presidential primary from March 24 to May 19, which is the scheduled date for the state's non-presidential primaries. It becomes the second state to do so in response to the coronavirus pandemic. Louisiana made a similar move yesterday, postponing its primary from April 4 to June 20.

Tuesday, March 17 is the third largest date - in terms of available delegates - on the Democratic primary calendar in 2020.  Voters in Florida, Illinois, Ohio and Arizona will cast their ballots. A total of 577 delegates is available. This trails only Super Tuesday and April 28. The latter date is the so-called 'Acela Primary' across six East Coast states.

Here are the latest polling averages in each of those states, as of Saturday, March 14.  Note that we have only averaged polls released after Super Tuesday, March 3.  We've also plugged these averages into our Delegate Calculator (create your forecast here) to get a sense of how the delegate split might look.  

At this point, Joe Biden leads in each of the four states, with that lead largest in Florida, the most delegate-rich opportunity on Tuesday. It is quite possible that the former Vice President will more than double his current delegate lead over Bernie Sanders.

Update 3/14 9:00 AM ET:  Bernie Sanders has won the Northern Mariana Democratic caucuses. Sanders will earn four of the six available delegates; Joe Biden the other two.  

Democrats in the Northern Mariana Islands caucus on Saturday, March 14.  The islands are 14 hours ahead of Eastern Time.  Results may be available as soon as early Saturday morning, with six pledged delegates to be be allocated.

Louisiana's presidential primary will no longer take place on April 4, as concerns over the coronavirus have led the state to delay it to a later date. It is the first state to change a primary election date due to the pandemic. 

The primary has been rescheduled for June 20. That is after each party's approved window for holding primaries. It is possible this could impact the number of delegates Louisiana has at the conventions this summer, although that seems unlikely given the situation.

The postponement shouldn't have a significant practical impact on the race.  On the GOP side, President Trump is likely to clinch the Republican nomination this Tuesday. That day's primaries in Illinois, Florida and Ohio should give him well over the 172 delegates he needs to reach the required 1,276.  On the Democratic side, Joe Biden is likely to significantly expand his delegate lead on Tuesday and may well be the presumptive nominee by the end of the month.

Democratic Polling Averages & Delegate Estimates

Joe Biden and Bernie Sanders should receive delegates in each contest, although it might be a close call for Sanders in Mississippi. Washington's primary is conducted by mail, with a good portion of the ballots submitted before today. This may partially explain the narrower spread vs. today's other states and the fact that the three remaining candidates only add up to about 80% of the vote.  Sanders scored dominant wins in Idaho and Washington in 2016; these states have switched to primaries in 2020 making that difficult to replicate.
