Last week Jonathan Martin wrote a column criticizing Joe Biden for not trying harder to get support from never-Trump Republicans:
I reached out to every current Republican lawmaker who has refused to commit to Trump in the general election. Sens. Susan Collins (Maine) Mitt Romney (Utah), Todd Young (Indiana), Bill Cassidy (Louisiana) and Lisa Murkowski (Alaska) all said the same: they’ve not heard from Biden. “It is surprising,” Collins told me. “It’s especially surprising because President Biden does understand the Senate, he has personal relationships with some of us.”
Martin was both widely praised and widely mocked for this. But today brings news that Biden is starting to run a new campaign ad:
The 30-second ad, entitled Save America. Join Us, targets Haley voters in predominantly suburban battleground state postal districts where she performed well against Trump in Republican primary contests.... It [] signals how Biden, a longtime champion of bipartisanship, is seeking to reach across the aisle one last time, courting moderate Republicans who cannot stomach their own party’s nominee.
The Biden campaign sees an opening in continued Republican opposition to Trump even after he clinched the party nomination last month. Haley dropped out of the primary race after Super Tuesday on 5 March but pointedly did not endorse the former president.
This is not the same thing that Martin was talking about, but it's in the same ballpark. And it may be that Biden feels like he needs to till the soil a bit before asking prominent Republicans for their support. They're most likely to say no, after all, and once you've gotten a no it's hard to turn that around. Sometimes it's better to wait.
"Republicans for Biden" is an obvious strategy for the Biden campaign. And maybe he should be setting it up now rather than later. But he'll get there.
