The Muslim vote
Also worth noting is that many of the Muslims in America are not citizens, and the age distribution is skewed to the younger age groups. So if Muslims are 0.8% of the population, they are probably at best 0.5% of the voting age population.
Jews on the other hand are about 2% of the population, but almost 3% of the voting age population, given our own age distribution (more on the older side shall we say), and voting pattern (high turnout rate). In other words, Jewish votes in an election are maybe 6 times the Muslim vote total.
