BEFORE THE presidential election in 2000, George W. Bush was urged by an adviser to go after a category of voters who would love a business-friendly, socially-conservative message: Muslims. Mr Bush took the tip and it worked. In 2001, a survey of American Muslims (including those who cast no ballot or gave no clear answer) found that 42% reported voting for Mr Bush against 31% for his Democratic rival Al Gore. Among upwardly mobile Muslim immigrants, many of them professionals or entrepreneurs, the proportion voting Republican was much higher.

Now, however, with anti-Muslim sentiment ablaze among supporters of Donald Trump, and the president hardly discouraging it, that love-in is a distant memory. American Muslims are gaining political visibility, but only on the far left of the spectrum. Symptomatic of this shift is the election to the House of Representatives of two Muslim women (Rashida Tlaib and Ilhan Omar) who along with two female colleagues, also left-wing Democrats, have been taunted by Mr Trump and his supporters.

A huge change in Muslim sentiment was clear in the 2004 presidential race and confirmed by the 2008 contest won by Barack Obama. By 2007 some 63% of American Muslims at least “leaned towards” the Democrats, against only 11% for the Republicans. These figures have not changed very much since, according to Pew Research, a pollster. Among Muslims who voted in the 2016 presidential race, only 8% said they opted for Mr Trump (who had declared that “Islam hates us”) and 78% for Hillary Clinton.

Campaigners for Muslim political engagement reckoned that more than 1m were registered to vote in 2016, and that last year’s congressional elections saw an uptick in Muslims going to the polls. Pew estimates that about 3.5m Muslims live in America. At around 1% of the country’s population as of 2015, they were more numerous than Hindus (0.7%) or Buddhists (0.7%) though well outnumbered by Jews (1.8%). But that picture is projected to change fast with the Muslim share doubling by mid-century.
