CHARLOTTESVILLE, Virginia (Reuters) – U.S. President Barack Obama exhorted voters to keep faith in his policy agenda in a campaign stop on Friday for a Virginia congressman he has praised as one of his Democratic Party's most courageous politicians.

Obama flew to central Virginia for a rally on behalf of Tom Perriello, a first-term Democratic congressman who is in a tough re-election fight, two years after winning his seat in the U.S. House of Representatives by just 727 votes.
“In four days, you have the chance to set the direction of this state and of this country, not just for the next two years, but for the next 10 years and the next 20 years. You can defy the conventional wisdom,” Obama told a crowd of several thousand people in downtown Charlottesville.
The Friday evening event was the first time during the midterm election campaign that Obama has appeared at a rally for an individual House candidate, a White House spokesman said.
On November 2, Americans will vote for all 435 members of the House and 37 of the 100 members in the Senate.
