When Vice President JD Vance stepped on stage in Michigan on Monday, it was MAGA Inc. writing the check for the campaign event. It was a rare bit of spending in a battleground state from a powerful political organization that has mostly been missing in action this year.

With just over two months to go before the midterm elections, President Donald Trump is still sitting on most of his colossal war chest, and he’s been growing his money pile instead of spending it.

Even though the president and his team insist they’ll open their wallet soon, frustrations are growing as Republicans try to maintain control of Congress despite headwinds partially of Trump’s own creation. While the president remains the party’s best asset in turning out its base, he is historically unpopular, with low marks on his handling of the economy and the ongoing war in Iran that most Americans say was not worth fighting.
