US mid-terms: Are you voting?
US voters cast their ballots in mid-term elections on 2 November, amid an increasingly divided American political backdrop.
Republicans are hoping to benefit from anger over the US economy to win back control over both houses of Congress.
But the Republican Party itself has witnessed recent divisions within its own ranks.
The conservative Tea Party movement has already made a big impact, with several victories over mainstream US Republicans in primary elections to select candidates.
Republican strategists fear these candidates will not appeal to the wider electorate in November.
However, mid-terms often see losses for the party of a sitting president - in this case Barack Obama's Democratic Party - and this year polls also suggest an unusually strong level of dissatisfaction with incumbents.
