As Biden's popularity grows, Democratic candidates start to welcome him to the campaign trail

President Joe Biden is hitting the campaign trail for vulnerable Democrats after a string of congressional victories and with polls showing the commander-in-chief's approval rating inching upward.

Biden's foray into the midterm elections comes as the president's approval rating has increased slightly and Democrats are more optimistic about their chances of keeping the House and Senate. The morale boost is partially the result of Congress passing the White House's $739 billion climate and tax legislation as well as a key victory for Democrats in a New York special election for a prime congressional swing seat last month.

Biden, in particular, was in Wilkes-Barre, Pennsylvania, earlier this week campaigning with the Democratic nominee for governor. Also in attendance was Pennsylvania Rep. Matt Cartwright, who is one of the few Democrats to represent a district carried by former President Donald Trump in 2020.

"Your congressman, Matt Cartwright, is the real reason I’m here," Biden told the Wilkes-Barre audience. "He knows how to deliver for this district, which is so close to my heart."
