MILWAUKEE, Wis. — President Joe Biden will travel to Milwaukee on Wednesday for a re-election campaign event. The White House didn’t detail the timing or where exactly the president would visit but said his message would be the turn-around in good-paying jobs. From Milwaukee he will fly to Saginaw, Michigan – another factory city in a battleground state with Republican challenger Donald Trump. Meanwhile, the President’s campaign announced a $30 million six-week advertising campaign to highlight key themes from Buden’s State of the Union address last week. The campaign is aiming at minority communities. Also: By next month Biden expects bulk up hus campaign staff in seven battleground states from 100 now to 350. More than 100 field offices will be opened. Surrogates too are on the circuit too: Vice President Kamala Harris stopped in Madison last week, and First Lady Jill Biden visited Waukesha the weekend before.
