During a campaign stop in Texas, former Vice President Joe Biden, 77, riled up voters to get excited for “Super Thursday,” before correcting himself to “Super Tuesday,” the day on March 3 where more than a third of the delegates will be pledged for the Democratic presidential nomination.

“Look! Tomorrow is Super Thurs- Tuesday, and I want to thank you all,” Biden said.

It’s just Biden being Biden of course, who has made a series of similar slip-ups throughout the campaign since jumping into the race for the Democratic nomination last spring. Biden’s frequent missteps however have raised doubts about the candidate’s age and ability to successfully take on President Donald Trump this fall.

Biden’s latest gaffe comes as the former vice president reels into the biggest day of the Democratic primary with a resurging momentum aiming to reclaim his frontrunner status from Vermont Sen. Bernie Sanders. On Saturday, Biden’s 28-point blow out breathed new life into his campaign after poor performances in the first three contests where Sanders eclipsed the party favorite as leader of the pack.

Recent events just before the Super Tuesday primaries may also tilt the dynamics of the race in Biden’s favor with several “moderate” candidates ending their campaigns including Minnesota Sen. Amy Klobuchar who has decided to publicly endorse Biden in Texas on the eve of the Tuesday contests.

Former South Bend, Indiana Mayor Pete Buttigieg also dropped out Sunday but has refrained from making an endorsement quite yet.

In addition to Klobuchar, Biden also picked up the endorsements of several prominent Democrats including former Senate Majority Leader Harry Reid of Nevada and former U.N. Ambassador Susan Rice. The recent slew of high-profile endorsements in the wake of Sanders’ rise and Biden’s resurgence showcases the Democratic establishment’s desire to keep Sanders from clinching the nomination by coalescing behind Biden.
