Share Source: AP Photo/David Goldman We’re back to this crap again. Sorry, but how many presidencies do we have to go through to discover that this is simply a unicorn in American politics. Both parties are guilty of this in the grand crusade to build the permanent political majority or the durable majority. I’m pretty sure the Obama folks thought his coalition would be durable. Trump smashed it in 2016. George W. Bush’s group thought a national security umbrella could create a durable majority post-9/11. That was eviscerated in the 2006 midterms. As so many have noted, like Real Clear Politics’ Sean Trende, there are many ways to skin the electoral cat. Before George Will left the Republican Party over Trump, he aptly noted that public opinion is shiftable sand, therefore, there are no permanent victories in American politics. Why should we think it’s any different regarding voters?
