Last Call For Primary Positions, Con't

Ahead of tomorrow's Super Tuesday primary voting, Sen. Amy Klobuchar is leaving the race and endorsing Joe Biden.

Sen. Amy Klobuchar will end her presidential bid on Monday and endorse Joe Biden, a campaign aide tells CNN. 

The Klobuchar campaign confirmed that the senator is flying to Dallas to join the former vice president at his rally, where she will suspend her campaign and give her endorsement on the eve of Super Tuesday. Former South Bend, Indiana, Mayor Pete Buttigieg also will endorse Biden at the rally, a source familiar told CNN. 

Klobuchar's path to the nomination all but closed after she posted sixth-place finishes in Nevada and South Carolina, a sign that the Minnesota senator's surprising showing in New Hampshire would not be nearly enough to propel her toward the nomination. 

A Democratic official told CNN that the Klobuchar campaign was worried that the senator would lose her home state of Minnesota on Tuesday. Vermont Sen. Bernie Sanders, the race's front-runner, is holding a rally in the state on Monday night. 

The high point of Klobuchar's campaign came in mid-February, when a strong debate days before the New Hampshire primary led to a third-place finish in the state. But the showing even caught Klobuchar's campaign off guard, and a lack of organization on the ground in Nevada and South Carolina, along with the senator's inability to win over Latino and black voters, ultimately stalled her candidacy.

Former Democratic Senate majority leader Harry Reid also endorsed Biden today, and the timing could not be better for the former VP.

Democratic primary voters appear to be giving former Vice President Joe Biden another look after his victory in the South Carolina presidential primary and ahead of the key Super Tuesday contests.

A Morning Consult poll conducted Sunday found 26 percent of Democratic primary voters nationwide said they’d vote for Biden if the Democratic primary or caucus were held in their state today, up 7 percentage points since polling conducted ahead of Saturday’s first-in-the-South primary in the Palmetto State.

National support for Sen. Bernie Sanders (I-Vt.) fell 3 points, to 29 percent, while former New York City Mayor Michael Bloomberg remained in third place, with 17 percent.

Sanders saw his first-choice support shrink among black voters, leaving him in a tie with Biden, at 31 percent. Among Hispanic voters, who will play a prominent role in Tuesday’s contests in Texas and California, Biden’s first-choice support increased 9 points, to 21 percent, though he still trailed far behind Sanders, who has more than twice that share of support with the voting bloc.

With 33 percent, Sanders leads in an average of polling from the 14 Super Tuesday states, while Biden saw a 7-point boost, to 24 percent, following his South Carolina victory. Bloomberg, who’s staked his campaign on victories in Tuesday’s contests, is backed by 16 percent of Super Tuesday voters, down 4 points from the previous polling.

The latest poll of 2,656 voters who indicated they may vote in the Democratic primary or caucus in their state, which has a 2-point margin of error, was mostly conducted before former South Bend Mayor Pete Buttigieg of Indiana ended his campaign on Sunday night. Billionaire Tom Steyer, who dropped out of the race on Saturday night, was also included in the poll, coming in with 1 percent of the vote.

The issue for Biden is now Michael Bloomberg is on the ballot in the Super Tuesday states tomorrow, Michigan and 5 other states next week, Big Tuesday states of Florida, Illinois, and Ohio in two weeks, and Georgia in three.  That will be over half the states and nearly two-thirds of delegates decided by then.

How much will Bloomberg cut into Biden's share, and will it be enough to put Bernie in the lead?  Will Warren stay in or drop out and endorse Sanders? We'll find out a big chunk of that picture this week.
