A solid majority of Democrats (58%) in the Senate supported the Iraq War...I consider that to be substantial. Democratic support in the House for the Iraq War was lower but still quite significant (82 Yea, 126 Nay). Attempts to frame Democrats as widely opposed to the Iraq War (at least initially) are very misleading, if not dishonest.
If you think 57% of congressional Democrats voting against it doesn't equal wide opposition, despite a relentless push for legislative support that's up to you I guess.
Given your previous statements about Democratic support for the Iraq war I don't think you're in a position to call anyone else's descriptions of it misleading or dishonest.
