Asset or liability? Biden's momentum hasn't led to new invitations on midterm campaign trail

• Biden has trips to three Senate battlegrounds – Pennsylvania, Wisconsin and Ohio – this week.
• The president's approval ratings have increased. But it hasn't led to invites on the campaign trail.
• Biden's travel blitz comes after he warned "MAGA forces" threaten democracy in a speech last week.

WASHINGTON — During a trip to Wilkes-Barre, Pa. last week, President Joe Biden lavished praise on Pennsylvania's Democratic Senate nominee John Fetterman, calling him "a hell of a guy" and "a powerful voice for working people."

"He's going to make a great United States senator," Biden said. 

But Fetterman, the state's lieutenant governor, was not in attendance. The campaign said a pre-scheduled fundraiser forced Fetterman to miss the White House event on public safety.
