Biden should drop out

Joe Biden should drop out, to make room for more effective candidates who are relatively similar to him, to stop the far-left, avowedly socialist Bernie Sanders from running away with the nomination. Now, nominating Sanders would be wonderful — for Donald Trump.

From 2000 to 2016, every Democrat who won the Iowa caucuses went on to win the nomination.

And the only time anyone has ever won the Democratic nomination without being in the top 3 in Iowa was when Sen. Tom Harkin overwhelmingly won his own state in 1992, leaving everyone else in low single digits. That's the rare exception that proves the general rule.

The full results still aren't in yet (days later!). But with 71% reporting, Biden is a distant fourth to Pete Buttigieg. Biden has 15%, while Buttigieg is currently at 28% (in state delegate equivalents).

The point isn't just that Iowa is a big deal. If Biden underperformed so badly there, he's going to keep underperforming. When you face the daunting task of beating the incumbent president in a good economy, you don't want an underperformer.

It's time to bring Biden's third presidential campaign to a graceful end. The sooner the better.
