GOP candidates are already pummeling each other in monthslong advertising free-for-alls, fights intensified by unprecedented television spending. The parties’ approaches in money spent and messaging could hardly be more different so far, as is the mere number of contested races: For Republicans, there are more than a dozen states where GOP candidates are attacking each other in bids for Senate nominations, while Democrats have unresolved primaries in just two key states — neither of which have turned vicious yet.

The difference is especially pronounced in Pennsylvania. As the Democratic frontrunners Lt. Gov. John Fetterman and Rep. Conor Lamb run ads arguing why they can win in one of the nation’s top battleground states, GOP candidates there have dropped a record-shattering $35 million on TV — the vast majority coming from Mehmet Oz and Dave McCormick, the leading Republicans, whose camps are framing the other as a “liberal RINO” and “Wall Street insider,” respectively.

“They’re doing what I want them to do, which is kick the crap out of each other,” said J.B. Poersch, president of the Senate Majority PAC, Senate Democrats’ flagship super PAC.
