US voters head to the polls on Tuesday, and their decisions have influence over daily routines for Americans and sometimes for the rest of the world - from climate change to global security:
"As globalization’s forces buffet the world..., the internal politics of any state can permanently alter course for other nations."
On the ballots is every seat for the House of Representatives and one third of the Senate. But turnout is low for the mid-terms when the presidency is not being decided: 37 percent of registered voters turned out for the 2010 congressional race compared with 54 percent for the 2012 presidential election, reports the Pew Research Center.
Compare that to Afghanistan turnout, despite threats of Taliban violence: 50 percent in the 2014 presidential race, 29 percent in the 2010 parliamentary race and 67 percent in the 2004 presidential race.
The percentage of women voting was 35 percent in the first round and 38 percent for the second.
Voting is not compulsory in either country.
