WASHINGTON: The blood on the dance floor has hardly dried and the victims have not been fully identified. But the carnage in an Orlando nightclub has become the backdrop of an already coarse and ugly presidential election, with Republican nominee Donald Trump showing no compunction in using the tragedy as a campaign weapon.In a series of tweets and statements in the hours after the worst terrorist attack in America since 9/11 -- with the highest fatalities in a lone-wolf gun assault -- Trump excoriated his Democratic rival Hillary Clinton and President Barack Obama , painting them as weak --and possibly treacherous --leaders on the issue of terrorism.Their ''political correctness'' stopped them from even using the expression ''Radical Islam'' which he felt was behind the attack. He went even further in attacking Obama.''Is President Obama going to finally mention the words radical Islamic terrorism? If he doesn't he should immediately resign in disgrace!'' Trump tweeted soon after the attack, saying while he appreciates the ''congrats for being right on radical Islamic terrorism,'' from his followers, he wants ''toughness and vigilance.''For the same reason – not mentioning ''radical Islam'' – he also wanted Hillary Clinton to quit the Presidential race.On Monday, Trump carried his attack on Obama to the TV studios, going as far as to suggest that he may be a closet Muslim with Islamist sympathies.''We're led by a man that either is not tough, not smart, or he's got something else in mind,'' Trump said conspiratorially in one TV interview. ''And the something else in mind, you know, people can't believe it. People cannot--they cannot believe that President Obama is acting the ways he acts and can't even mention the words radical Islamic terrorism. There's something going on. It's inconceivable.''Under pressure, Hillary Clinton said she was fine with calling it ''radical jihadism or radical Islamism, I think they mean the same thing.''But Trump has swooped down on the carnage to display national security credentials that seem based on muscular exclusivity''If we do not get tough and smart real fast, we are not going to have a country anymore. Because our leaders are weak, I said this was going to happen – and it is only going to get worse. I am trying to save lives and prevent the next terrorist attack. We can't afford to be politically correct anymore,'' he said earlier in a self-congratulatory statement that focused largely on terrorism and its connection to immigration, with barely a word on gun laws or homophobia, which is part of the fabric of fundamentalists in all religions, including Christianity.Reporting that Orlando killer shouted ''Allah hu Akbar'' as he slaughtered clubgoers, Trump went on to indicate that he would advance his agenda of a Fortress America that would begin with blocking the entry of Muslims into the United States.''We admit more than 100,000 lifetime migrants from the Middle East each year. Since 9/11, hundreds of migrants and their children have been implicated in terrorism in the United States,'' he said, claiming that, ''Hillary Clinton wants to dramatically increase admissions from the Middle East, bringing in many hundreds of thousands during a first term – and we will have no way to screen them, pay for them, or prevent the second generation from radicalizing.''The fact that Omar Mateen was a New York-born U.S citizen of Afghan parents seemed to make little difference to Trump, as he spoke of the ''need to protect all Americans, of all backgrounds and all beliefs, from Radical Islamic Terrorism -- which has no place in an open and tolerant society,'' oblivious to the irony of himself proposing a closed, intolerant society.''Radical Islam advocates hate for women, gays, Jews, Christians and all Americans,'' he railed, pledging quite paradoxically that is he ''going to be a President for all Americans, and going to protect and defend all Americans.''Many conservatives joined Trump in crucifying the Obama administration and Democrats in general for what they perceived was weak-kneed response to possible Muslim infiltration of the United States''We need to limit the nation from taking any more Muslim immigrants who someday could also become citizens or permanent residents. It’s also time to deport all Muslims who are in the U.S illegally and on student and other types of temporary visas,'' proposed Larry Clayman, a conservative activist and founder of JudicialWatch, who accuses Obama of covering up ''his Muslim heritage and connections.''
