At least one half of the Libertarian ticket understands the threat that Donald Trump poses. Bill Weld, former Republican governor of Massachusetts, says he will now focus exclusively on defeating Trump.

As the 2016 presidential election nears its conclusion, tough choices are being made:

Libertarian VP candidate Bill Weld told the Boston Globe that he plans to focus exclusively on attacking Donald Trump for the remainder of the campaign — essentially admitting that running mate Gary Johnson can not become president.

Trump has Weld’s “full attention,” he explained, because his agenda is so terrible it’s “in a class by itself.” “I think Mr. Trump’s proposals in the foreign policy area, including nuclear proliferation, tariffs, and free trade, would be so hurtful, domestically and in the world, that he has my full attention,” Weld said.

The Boston Globe reports:

Weld’s comments in a Globe interview mark a major shift in his mission since he pledged at the Libertarian convention in May that he would remain a Libertarian for life and would do all he could to help elect his running mate, Gary Johnson, the former Republican governor of New Mexico. But things have changed. Johnson has committed several high-profile gaffes in recent weeks that revealed apparent weak spots in his foreign-policy knowledge.

Gary Johnson is a deeply unserious candidate and a terrible choice for young voters. As Election Day draws near, third-party voters have to make a choice: Stop Trump or effectively give him their vote.

Bill Weld is taking responsibility and showing how it’s done.
