Why There's No Room for Mike Gallagher in the House

Rep. Mike Gallagher , a Wisconsin Republican , announced he won't run for re-election.

He is perhaps his party's most effective critic of China ’s rise and its growing alliance with Russia .

Gallagher was long seen as a fast-rising star in his party, for both his political acumen and his foreign policy chops.

Gallagher may be trading a Princeton- and Georgetown -educated expert in national-security policy and history for a glorified meme-maker.

Gallagher 's exit represents the loss of one more potential Republican safeguard in Congress against some of the diciest moves the White House might try to execute during a potential second Trump administration.
