DeFazio will underperform but he'll probably win in the end. Since OR is likely to gain a seat after the 2020 census, which is likely to be a Republican one, it's likely his district will be shored up in redistricting.
Democrats would be idiots to not give this district Bend (which is wasted in OR-02) and then give some of its more Republican territory to OR-02.
Ok so then Dems quorum bust Republicans in Georgia and Florida if they try aggressive gerrymanders there.
Ok? They can try although the obstacles in those states are more procedural, in Oregon its part of the state constitution. IIRC the Texas state senate tried doing this , although in the end it failed. However it did work for the Oregon senate and the climate bill. Im guessing quorum busting is generally looked down upon although probably not as much when it comes to redistricting.
IIRC it failed in Texas b/c the Dems wimped out.
