A day after the Democratic Congressional Campaign Committee released a poll showing Rep. David Cicilline, D-R.I., staked to a lead, Cicilline's campaign announced an internal survey showing nearly identical results.

In a three-way matchup between the freshman House member, GOP challenger Brendan Doherty, and independent David Vogel, Cicilline drew 46 percent support in the poll, versus 36 percent for Doherty and 7 percent for Vogel.

Forty-six percent is dangerous territory for an incumbent, although Cicilline draws increased support in a head-to-head matchup against Doherty, which is important to consider because independents often over-perform in poll results compared with actual election results. Matched up against just Doherty, Cicilline led the Republican, 51 percent to 41 percent.

The survey was conducted for the Cicilline campaign by The Feldman Group, which interviewed 500 likely voters on Sept. 13 and Sept. 15-17. The poll's margin of error was plus or minus 4.4 percentage points.
