WASHINGTON/NEW YORK (Reuters) - The mass shooting in Orlando, Florida has allowed Donald Trump to seize upon a familiar issue he has used to great advantage -the threat of Islamist militants and his plan to limit Muslim immigration to the United States, offering him what could be a crucial moment to re-boot his sputtering presidential campaign.
But while rank-and-file voters might respond positively to Trump’s renewed call for a ban on some Muslims entering the country, his reaction to the massacre showed few initial signs of winning over Republican foreign-policy figures who have spurned the New York mogul.
