Former Massachusetts Governor William Weld on Monday formally declared his candidacy for White House, setting him off on an extreme uphill climb to defeat incumbent President Donald Trump for the Republican nomination.

“It is time for patriotic men and women across our great nation to stand and plant a flag. It is time to return to the principles of Lincoln – equality, dignity, and opportunity for all. There is no greater cause on earth than to preserve what truly makes America great. I am ready to lead that fight,” said Weld in a statement as he launched his bid to try and topple Trump, who remains very popular with Republicans.

Weld, a very vocal Trump critic, also released a three-minute-long video highlighting his achievements during his two terms as governor of Massachusetts in the 1990s.
