"Maybe, just maybe, if we let the Republicans bend us over and up our infrastructure agenda, they'll be really nice to us and won't call us socialists during midterm season!"
If "bipartisanship!" is your biggest selling point, what you're implicitly telling voters is that the other political party makes valid points and should be included in the process. That's terrible politics and its why Democrats underperformed massively last year. The GOP campaigns on "Democrats are evil s and must be defeated" while Democucks campaign on "I'm go to Washington and work with Republicans on muh bipartisanship". It's an extremely weak campaign message that leads to horrible base enthusiasm.
The way you win elections is jamming a huge infrastructure bill through reconciliation and then campaigning on "Yeah, we did it our way because the GOP's way ing sucks"
