CHICAGO: Arab Americans running in several Illinois primary elections fell short of their goals on Tuesday, but so did candidates supported with millions of dollars in campaign contributions from pro-Israel Political Action Committees. In primary elections, voters select the candidates who will represent their political parties separately, Democrats or Republicans, in general elections. Several of the contests took place in communities with large Arab and Muslim populations concerned about wars in the Middle East. But in some cases, other issues appeared to determine election results.
