While Walsh stands nearly zero chance in a primary against Trump, who remains hugely popular among Republicans, the Times said he hopes to appeal to conservatives like himself who have soured on Trump.
Undeterred from pressing ahead with his candidacy, Walsh said, "I think this thing... will catch on like wildfire".
Walsh has acknowledged there's little chance his candidacy will result in Trump losing the party nomination, and he is instead focused on offering GOP voters an alternative vision for the party. Like Weld, Sanford and Trump himself, Walsh also espouses a more restrained approach to foreign policy, criticizing US intervention overseas. Two other former Governors, Mark Sanford (R-SC) and John Kasich (R-OH), are also said to be mulling bids.
USA officials say Macron surprised Trump at hotel.
"It can only contribute to more robust dialogue and that will be good for the country", he said.
Walsh said that he regrets some of the comments he has made. "I don't want him (Trump) to win".
But he has since soured on Trump, criticizing the president over growth of the federal deficit and writing in a New York Times column that the president was "a racial arsonist who encourages bigotry and xenophobia to rouse his base". The personal ugly politics. "And now we've got a guy in the White House. that's all he does".
