Democratic leaders are engaging in a cynical bait-and-switch in a “deal” on a federal infrastructure bill. Every Republican in the Senate, including those who initially signed on to what they thought was a good-faith agreement, should reject the Democrats’ ploy.

The difference in the two parties’ approaches has been obvious for months. Republicans were willing to spend about $500 billion on things traditionally considered “infrastructure,” such as roads, bridges, ports, airports, and broadband. President Joe Biden initially proposed a behemoth plan costing more than five times that amount, which included all sorts of liberal wish-list items, such as “job training,” housing, and union organizing, that have nothing to do with traditional infrastructure. Indeed, even by liberal network CNN’s accounting, which gives the benefit of the doubt to Democrats in all matters, only 30% of Biden’s proposal was really infrastructure. (Republicans said it was just 7%.)
