Mid-term elections 2018: Race rows mire campaign home stretch

Race-baiting allegations have mired the home stretch of the US mid-term elections, turning it into one of the ugliest campaigns in recent times.
US networks have withdrawn President Donald Trump’s ad about a cop-killing illegal immigrant.
Meanwhile, racist automated calls targeted prominent African-American candidates in Florida and Georgia.
Control of Congress is up for grabs in Tuesday’s poll, which is being seen as a referendum on Mr Trump.
His ability to govern in the final two years of his term will hinge upon the outcome of votes for all 435 seats in the House, and 35 of the 100 Senate seats.
The Republican president – who has been holding barnstorming rallies nationwide, even though he is not up for re-election this year – campaigns in Ohio, Indiana and Missouri on Monday.
In the weeks leading up to the polls, Mr Trump has escalated his rhetoric about his opponents and divisive issues such as immigration, warning voters against Democratic “socialism” and “an invasion” of criminals from the Central American migrant caravan.
His sharp language has appeared to energise conservative voters, but critics have condemned Mr Trump’s tactics as fear-mongering.
